As some of you may know, VOIP is possible with our phone, but require a VOIP cab, and editing a file to enter the SIP settings. Or, alternatively, there are a few applications out there like Skype, or Fring.
But the universal problem for all implementations thus far is that they all route the sound out the speaker on the back of our phone!
Today I came across BT Total Broadband Anywhere: http://www.productsandservices.bt.com/consumerProducts/displayTopic.do?topicId=24561
This service clearly uses VOIP!
Obviously BT has fixed this problem! So two questions:
Could any of the ROM hackers here extract the fix for the rest of us to use?
Can a BT user with this service test Skype and see if the speaker problem exists?
Thanks!

BT Voice over internet is lame, you can hardly hear people, it cut's out during calls etc.
I have just reset my phone from BT due to bad programming on BT's behalf, so no voip i can live without, battery life was lame 2.
Yeah, but those issues may just be with BT's implementation of VOIP. Can you remember if when you were on a voip call the sound was correctly routed through the earpiece? our longstanding issue is that the sound was coming out of the back of hte phone (speaker) and thus voip caloing was useless in public places.

It was proper routed through the earpiece.
With AGEphone Mobile 2 Speakerphone Edition there is no need to worry about this in the long run: We are planning to add support for the internal speaker to all relevant devices!
I was wondering if Desire works OK with bluetooth hand-free devices. Someone who can tell us about it? I use it a lot on my car and it's a basic point for a mobile phone. I would really appreciate any feedback about this.
Thanks.

Works well with my BT Parrot CK3300 kit.
Ive got a Pioneer 7100BT winging its way to me, that has A2DP, im hoping it will work well with my Desire. Will post results when i get it and install it tomorrow.
Seems to work ok with my Standard Motorola headset.
Hoping to be able to est it with a bluetooth stereo soon.

Hope someone can figure this out:
I've had experience with 3 mobiles connecting to the built-in bluetooth in my car (HTC Tytn II, HTC Hero and Nokia e71) my concern is the following:
With the Nokia, when I get a call, I hear the phone ringtone through the car speakers. But with both HTCs I couldn't, I hear the default car ringtone, which is REALLY annoying.
The nokia e71 has the following bluetooth specs:
Bluetooth version 2.0 with Enhanced Data Rate
- Bluetooth profiles: DUN, OPP, FTP, HFP, GOEP, HSP, BIP, RSAP, GAVDP, AVRCP, A2DP
does anyone know if one of the these profiles is responsible for this? which one? I hope it would work with the Desire.
by the way, does making the phone visible before connecting make any difference? (just wondering)

No problems at all. Just a standard pairing; it took less than a minute to auto sync the address book and I was ready to go.
I've never had problems with this kit; have sync'd numerous WinMo devices, Blackberrys (is that the plural?!) (still active for work) and now the Android device.

VAG cars need phones that use the RSAP Bluetooth profile, it's a bit of a wierd profile and stands for Remote Sim Access Profile, now looking this up for you I can only see some blackberry and Nokia phones that have this profile.
Bluetooth phone prep is a bit of a waste of time at the moment as the company who writes the software are not fully integrating there systems with everyone else, they are also not following standard A2DP procedures, I would imagine this is due to a partnership thing with people like Nokia and company cars etc.
Next time save the 600 quid or so you pay to have bluetooth prep and get a decent stereo like I have in my Audi, unless you got satnav too then you are stuffed
I have enclosed a link on VAG group phone prep and HTC phones, make sure your SIM card is of the new Variety
http://audiforum.us/multimedia/11189-audi-bluetooth-rsap-adapter-htc-touch-pro.html
I've had mixed results.
In my car the Desire works perfectly with the Parrot CK3300. I get full bluetooth contact sync, voice dialling works fine (the CK3300 does the voice recognition as the Desire doesn't do it over bluetooth) and calls come through loud and clear.
The wife has the lower CK3000 Evo. This doesn't have a display, so you send contacts to the kit over bluetooth and then record voice tags against them so that the kit can do voice dialling. Unfortunately the Desire refuses to send contacts to it and claims that the kit doesn't support sending contacts over bluetooth. This unfortunately means the wife can use the kit for incoming calls, but has no voice dialling for outgoing calls when she also upgrades to the Desire on Saturday when her contract's up.
Dae.
But what about voice dialling over Bluetooth with any of those?
The Android OS doesn't support voice dialling over bluetooth yet.
That's why I use the Parrot CK3300 - it does it on behalf of the phone. It basically syncs the phonebook to the kit. You then record the voice tags into the kit and associate them with a contact. You can then voice dial, which the kit will match up to the contact and dial using the phone.
Even when I've had phones that do support voice dialling I've always found the Parrot more effective.

Thanks for the explanation. I happen to own a VAG car, A4 B8 with concert radio.
So SAP profile is different than RSAP profile? Could this be responsible for the phone ringtone not going through the car speakers? Because everything else works perfectly, it pairs and connects automatically, syncs contacts and make/receive calls, except for the ringtone issue! Which sounds like an ambulance siren.
What stereo system did you install?

That's not good to read at all if I remember correctly I think I have on my car the same parrot model as your wife. My parrot is working perfect with Omnia and Xperia but I was afraid it wouldn't work with Desire and it seems I was right to be afraid. That's a huge problem for me.

It's a big deal for her too. I'm hoping that it'll be fixed in a future update. I'm glad we thought to check it before she upgraded to the Desire. She's going to hold off upgrading until this issue is resolved as she spends a lot of time in the car and it's not cheap to upgrade the handsfree kit. It's a deal breaker for her.

I installed a Blaupunkt MP68 but would not recommend it as it's pretty old now, the good thing was in the day it matched the Audi Red dials perfect and was German so I stuck with it.
All the Pioneer new series of BT headunits have Parrot BT built in so I would recommend one of those.
hmmm ... where does one go to get at slightly more advanced settings for BT? The Settings>Wireless & Networks options are very basic. I'm hoping to be able to tweak something to make it start working with my Audi A5. I suppose I'm asking is there anything like Sim Access Profile or Jetware out there?
Anyone any ideas? I searched Marketplace but nothing relevant came up.
I have found that my motorola headset keeps connecting and disconnecting like it is going out of range.
Thing is, it can be in my pocket about a foot from my headset and still disconnect and reconnect several times a minute.
Just had the new kenwood deck installed... Should do almost anything. I have my incredible paired up and calls are clear. Problem is A2DP audio streaming. Does not work. No A2DP device is found. Yes, the manual gives directions to play streamed audio once bt is synced. Well, its synced, got my phone book on there, and calls are being made.
Any thoughts or ideas to get streaming audio?
I don't have any help to offer, but I am experiencing the same problem with my Pioneer FH-P8000BT. Pairs for phone calls with no issue and everything is clear, but the radio does not even "see" the device as being available for A2DP.
I previously paired a few different HTC phones (all running Windows Mobile) with this radio with no issues. I'm hoping it's a simple fix, but I can't find a single thing in the settings that I haven't played with to try and get it to work.
I have an Alpine HU with an Alpine KCE-400BT bluetooth add on. My streaming audio is working, although I don't get any song/artist info on screen. I do have an issue where the phone doesn't sync up all the time. It syncs up great in the morning. If I stop for gas or something (turn off the car briefly) and get back in, then the radio won't see the phone until a call comes in or is started from the phone (or I toggle BT on/off).
You might check with Pioneer on any firmware udpates.
My incredible works great with my Ford sync system. It always connects, calls are loud and crisp, and streaming bt audio works great. I use it to listen to Pandora all the time.

I have seen other people post issues with having bluetooth on the phone enabled before the car is on. If you turn the car on first and then the phone's bluetooth they said it worked fine.
I have Kenwood HU and my phone won't pair with it. my Blackberry Paired with it fine, and even did A2DP, and worked awesome...now......nothing.
Been looking for some answers as to why, but after calling Kenwood they said it's a software update that is missing.
however, seeing as some people are getting it working fine....I am suspecious.
Kenwood 4160 working, actually better
My 4160 and serveral WM units worked, but the A2DP always had to be turned on by going into the menu every single time I wanted to listen to anything from the phone, but the Incredible does it by itself every time perfectly.
I have a Pioneer AVIC N4 and the audio for both calls and music works just fine out of the box.
I have the kiv-bt900 also, and it is my understanding that it does not have A2DP. I believe the A2Dp in the manual is referring to the KIV-700 with the add on bt module.
From page 67 (of the downloaded manual from Kenwood)
KIV-BT900
Supported Bluetooth Profiles:
Version: Bluetooth Standard Ver. 2.0
Profile: HFP (Hands Free Profile)
OPP: (Object Push Profile)
PCAP (Phone Book Access Profile
SYNC (Synchronization Profile)
I thought it had it too when i bought it. Maybe a future update will enable it though??
What does A2DP mean please?
it stands for Advanced Audio Distribution Profile. In simple terms, it's stereo audio transferred from one device to another via bluetooth. Example: Music from a phone/mp3 player to stereo bluetooth headphones, head units etc..
Thank you.

Well damn. The deck was sold to me from car toys (local vendor) under the pretense that it would do zune (works great) and A2DP...
Usb works great too... I was thinking of formatting a laptop drive to the mac file system (hfs) and hooking it up to the usb port to get a200GB drive of mp3 and video since it supports ipods. (works on xbx360, why not here?)
OK so a small fix, but not the end result.
with my Kenwood head unit I can make it work as long as I don't let it download the phonebook. and that is no problem since the phone sits on my dash in the car dock. but the problem is that EVERY time I start up my truck, or after I end a call it asks to re-download the phonebook.
it kinda irks me, but I cannot get it to stop asking, no setitngs on the stereo work.
I emailed Kenwood about possibly releasing a firmware update to include A2DP to the kiv bt900. They responder saying that there isn't enough demand for the feature for them to create a firmware update. So if we get enough people contacting them and requesting that feature, they will release and update. So you guys should all contact them to increase the demand for this feature. Hope this helps.
Here is exactly what they responded:
"I understand that you're inquiring about the KIV-BT900's Bluetooth features. We do apologize for any difficulties that you've experienced with this item. Unfortunatley, we cannot assist you with any firmware updates at this point since this model was just recently released to the market. Our company has not received enough demand for this feature which prevents us from developing or releasing an update for the KIV-BT900 unit. We may release an Bluetooth update in the future, however it's hard to determine at this time."
I'm willing to start complaining and sending some emails out to them. What email address did you send it too? I just got the player and that is def the only thing missing to make it complete for me.
I tried emailing the regular support channels and got the below message.
Thank you for contacting Kenwood USA Corporation. We value you as a Kenwood customer and appreciate the opportunity to be of assistance.
I Understand you are inquiring about any updates to allow the A2DP profile.
There is currently no available updates and there hasn't been information on upcoming updates for the A2DP profile. We ask that you check back at a later date to verify if one is posted through the www.kenwoodusa.com website.
We apologize for any inconvenience.
Please feel free to contact us again with any additional questions.
I spoke with a rep and they mentioned that A2DP missing from the unit is the most often called in issue about the unit.
I have a KDC-BT948 with the same issue. They removed A2DP and put in Pandora instead..and it only works through iPhone, which then uses up wireless data on a cell phone plan. So Android, MS phones, and any other bluetooth device can no longer be used with a Kenwood Car Stereo. Someone at Pandora really made an impression at someone in Kenwood. It is too bad that they are limiting consumers with their choice which ultimately limits their sales and increases complaints.
Should have everyone go do this and request a fix.
Go to the Kenwood Contact page and send an email
This is what I sent
I have purchased the KDC-BT948HD radio.
Where I am overall happy with many of the features, looks, variable colors, and excellent sound quality of the unit, there are several things that I am extremely dissapointed in and would like to see an update released to resolve them.
1. SMS Received message on the unit: Might be useful to some, but to me it is a dangerous distraction while driving, especially at night. It has me take my eyes off the road to look at the unit and makes me want to look at my phone to read/send texts. Texting and driving is illegal in many states and there should be a way on the unit to allow a selection to turn this feature off.
2. BT Audio (A2DP) is missing. I have an Android phone with my music on it. Alone there are more Android phones than iPhones in use today. I wanted to have Bluetooth streaming audio so I can play my music from my phone to the unit. For such a high technology unit, it should be part of the firmware and flexibility to the consumer to use their device with more options. The previous year units had this enabled and seems to be disabled now replaced by a focus on a wired Apple connection and Pandora. Forcing use of Pandora also forces consumers to use up data rates on their wireless plans. If A2DP were enabled, more consumers could enjoy the product integration with standard BT devices offered by Apple, Android, Microsoft and many others. All could enjoy the music and audio applications on their devices including Pandora. I would like to request that A2DP be added to the firmware and source selection on this device. I should yield increase product ratings and sales as web searches show many complaints about this issue.
I would value your feedback on these points and potential solutions.
Best regards

Just wondering what bluetooth services people are seeing on there WP7 phones.
I have a HD7 on T-Mobile USA and it's only advertising the following to my Windows 7 computer:
A2DP
Headset Audio Gateway
Remotely Controllable Device
Thanks
a2dp as a service for the phone? not sure, but my friend bought the hd7 on my recommendation and he can't get audio for video files through a2dp and its killing him
hopefully wp7 has some cool tricks up its sleeve based on what you got there
I'm interested in four bluetooth profiles, if and how they are compatible and work.
- A2DP
- AVRCP
- Handsfree
- Bluetooth HID for Keyboard
any news mostly about the BT HID Keyboard?
I found this on Microsoft Support site:
Windows Phone 7 supports the following Bluetooth user profiles:
Advanced Audio Distribution Profile (A2DP 1.2)
Audio/Video Remote Control Profile (AVRCP 1.0)
Hands Free Profile (HFP 1.5)
Headset Profile (HSP 1.1)
Phone Book Access Profile (PBAP 1.0)
http://support.microsoft.com/kb/2449475
This is the first device I have seen that supports SMS over bluetooth. If you have a Ford product with SYNC, you can use SMS over bluetooth. It also works with my Kenwood head unit. Basically, you can see incoming messages and, in the case of SYNC, send canned replies from the head unit. On my Kenwood, there is actually an on-screen keyboard to send any message you like. Cool stuff really!

same problem with my htc trophy. audio for video files only plays through the loud speaker and not through the bluetooth headset. I tried the blueant q1, jabra stone and jabra extreme with the same results
i have a Samsung Focus and i am having the same issue with no BT audio from videos. i tested the HTC Surround and LG Quantum at the ATT store with the same results. i am using a Jabra BT3030 which worked perfectly on my Microsoft KIN, audio streamed and play controls (Play/Pause/FF/RW) worked.
A2DP
Does anybody know if an A2DP video fix is coming up in the NoDo update? I'd say it's way more important than copy-paste, but regardless of importance, it is an important feature.
Any news?
noone knows outside of MS as far as i'm aware. we only know about copy/paste and app performance improvements because they told us. only time will tell if they actually fixed the issue.
hands free car kit and voice activation
When my LG is linked to the Bluetooth hands free car kit (Landrover) the voice activation doesn't work.
It opens but it doesn't "hear" anything
Since this is about the only time i actually need voice activation it's a bit annoying
Anyone have any ideas?
I totally agree about this bug. Who the F cares about copy and paste? How about turn-by-turn navigation for Bing Maps like was released last year for WM6.5 ?
Hey guys I have the official nexus car dock and was wondering if there's a way to get calls to come through the car speakers? I have a phono going from phone to stereo which handles music navigation etc fine but as soon as a call comes in it goes straight to speaker phone. Is there something I'm doing wrong or is there a 3rd party app that can handle it better?

The only workaround I've found for this is to use SIP calling, i.e. set up a VoIP account and use that for calls - everything is routed properly through the dock audio output. This is nicely integrated in Android / Phone.apk, you don't need a third-party app.
Forcing regular GSM voice calls to go through the dock audio output might require some kind of kernel modification, I haven't found anything in the AOSP codebase that would change this behaviour.

Setting up a VoIP account does that mean they'd have to call me on a seperate number or will it push it straight through to my normal number?
Sent from my Galaxy Nexus using xda premium
Correct, a VoIP account would be a separate number, but depending on the provider and the type of number you might be able to set up forwarding (at the provider end) from your regular number to your VoIP number.
easiest solution and future proof to boot: get a bluetooth headunit !
Have a Kenwood KDC-BT60U, a pretty basic model, payed 200 for it, and it rocks: can access latest incoming, latest outcoming, missed, phone book, plus it has A2DP.
Get a bluetooth car stereo. Or some kind of interface kit. Google for it.
