In the OS6 documentation. If you add voipMode=true as a parameter for audio recording, CMDA phones will be able record and playback at the same time. Has anyone tried this? It did not work for me at all. Also, this parameter supposed to make the recorder and player work in a way that's more compatible with other voip devices. However, the documentation never explain what kind of compatibility is this supposed to have. Anyone?

This seems to be just another red-herring that RIM has dreamed up to give developers false hope. You are supposed to also specify the correct bit-rate and such... I tried it on a GSM device in the hope that I could actually get full-duplex recording and playback to work for audio/x-gsm on a Torch. But it didn't help for that either:

"capture://audio?encoding=audio/x-gsm&rate=8000&bits=13&channels=1"

for example, seems to start up the recorder, but the moment you add in:

"capture://audio?encoding=audio/x-gsm&rate=8000&bits=13&channels=1&voipMode=true"

You just get: Exception starting recorder 

[Aviator168]

No. If you put the voipMode=true as the first parameter, it will work.

My problem is with the CDMA phones. It suppose to allow duplex audio on the CDMA phones running OS6; but when I test it on the simulators, it does not do the job.

Have you tried it on an actual device?

[Aviator168]

Not yet. I hope it will work on an actual device.

Which CDMA phone can run OSv6 in the US?

[rcmaniac25]

BlackBerry Style

Also, do you know if it works on OS 5.0? I know it was found in the 6.0 docs but for all I know this is one of those "it's always been there but we just so happened to let people know about it now" components.

[Aviator168]

You can never tell if it was there in OS 5. It is string parameter, it might just ignored it in OS 5. Now the cat is out, they have to support it by the doc and the doc is very clear that CDMA phones running OSv6 will be able to do full duplex audio.

[rcmaniac25]

Yep. If you end up trying it on a Style and it doesn't work, I'd say PM MSohm to see if he knows anything.

[Aviator168]

Definitely do that. One of my phones is way passed for upgrade. We are waiting for a different phone other than the Style. If the CDMA phone can do full duplex, all we need is data plan to get unlimited voice/text/email.

ok... you are right, if you set voipMode=true as the first parameter the recorder does actually start up. But the moment i start up another player it dies. This of course is only with gsm. With two PCM players it's fine, and with a PCM recorder and a GSM player it also seems to be ok. But full duplex on a GSM stream doesn't seem to work, even on a GSM phone.
