However the moment we switch to iOS SDK 3.2 everything works fine. So right now, we are building PJSIP on 3.2 - once built on 3.2, our application when deployed in an iphone 3G (3.x) or iphone 4 (4.0.1) works fine. Our conclusion therefore is that pj1.6 has some issues in the audio driver for iphone when compiled with iOS SDK 4.0 - correct?
We are able to use 1.6 on iOS 4.0.1. Sorry, one of my teammates dealt with the build issues so I can't offer any advice.

Alternately, we do not receive any notification from PJ when init is complete, so when we start our VoIP client, we have no idea when PJ is ready to make a call - so we cannot display a "initializing" message that g goes away when PJ is ready to make calls.
You can get the notification via pjsua_config.cb.on_reg_state - just beware of threading issues. This is how we use it.

pjsua_config_default(&(iCfg));
pj_strdup2_with_null(iPool, &(iCfg.user_agent), "DV iPhone App v1.0");
// Initialize application callbacks
iCfg.cb.on_incoming_call = &OnIncomingCall;
iCfg.cb.on_call_media_state = &OnCallMediaState;
iCfg.cb.on_call_state = &OnCallState;
iCfg.cb.on_reg_state = &OnRegState;
iCfg.nat_type_in_sdp = 0;
iCfg.max_calls = 1;
iCfg.thread_cnt = 1;
iCfg.force_lr = 0;
}

InitRTPCfg();

status = pjsua_init(&iCfg, &iLog_cfg, &iMedia_cfg);
if (status != PJ_SUCCESS)
goto error;

We are successfully using pjsua_call_dial_dtmf...
How would I get ahold of PJSIP for Android? Which versions of Android are supported? Is it stable? Does it work well? Blah, blah, blah.
Thanks,
