have you ever tried iphonesound.c rewritten by Samvel, author of Siphon project.
Maybe it would work well?

Subject: BUG: iPhone and bluetooth
After experimenting with these for few days, I have come to the conclusion that there is possible bug in PJSIP coreaudio_dev.c
When I try to route input to the bluetooth using
pjmedia_aud_dev_route route = PJMEDIA_AUD_DEV_ROUTE_BLUETOOTH;
pjsua_snd_set_setting(PJMEDIA_AUD_DEV_CAP_INPUT_ROUTE,
&route, PJ_FALSE);
I can hear static for 1 - 2 seconds on the bluetooth headset and then nothing, the audio is then continued to be played via the iPhone earpiece.
Here is the log of when this occurs, from the log it looks like it successfully changed route to bluetooth but for some reason it automatically changes back to the earpiece. Any idea?
