Subject: Re: Enabling VAD/CNG context based - msg#00389List: voip.wengophone.develHello, is it possible to enable VAD/CNG only if CNG was negotiated between both parties? If yes, how? When I test it now, if I enable VAD/CNG on one side and call another who does not support this feature, the first side has VAD enabled and does not send voice packets, which on the other side appears very annoying. The first side should disable VAD if CNG payload was not negotiated. Thanks for your help. Normally phApi tries to negotiatie the CNG payload... take a look in ph_call_retreive_payloads.... but frankly this is note very well tested....

So, I compiled Global.lib Exosip.lib Osip.lib Ortp.lib netlib.lib and several codecs like speex.lib, ilbc.lib,gsm.lib, etc.. Now, I'd like to realise a simple main() to call somone... What I think I need, and I should to is: Configure Phconfig struct call Phinit() call phaddauthinfo call PhaddVline (I don't really well understand what is a Vline, if someone can telle me brievouisly...i'm lost with the cid concept) call phlineplacecall You can take a look on wifo/miniua/minua.c for simple command line softphone application example. Vline is a Virtual Phone Line, which specifiies coordinates of your SIP provider (server, and proxy) and a name you use to regsiter with the provider... cid is callId.... You can place several simultaneous calls, cid discrimnates between them. Vadim ___________________________________________________________________________ Nouveau : téléphonez moins cher avec Yahoo!
