c# - Audio feedback using RIL Audio on SmartPhone -

We are working on a SIP softphone and when we call from one phone to another, we get the audio response However, when we call our app from a normal SIP phone (software or hardware), it all works well - this is when call from one phone to another phone starts RIL audio To do this we have the code used here:

 < Code> public static zero InitRILAudio () {IntPtr res; RILRESULTCALLBACK result = new RILRESULTCALLBACK (f_result); Inform RILNOTIFYCALLBACK = new RILNOTIFYCALLBACK (f_notify); Res = RIL_Initialize (1, result, notify, (0x00010000 | 0x00020000 | 0x00080000), 0, outside HRil); If (res! = IntPtr.Zero) return; RadioteVision FOODIO AUDIODOVINFO = NEW REALAUDODEVISONFOO (); AudioDeviceInfo.cbSize = 16; AudioDeviceInfo.dwParams = 0x00000003; // RIL_PARAM_ADI_ALL; AudioDeviceInfo.dwRxDevice = 0x00000001; // RIL_AUDIO_HANDSET; Audiovisivefondroidxdice = 0x00000001; // RIL_AUDIO_HANDSET; Res = RIL_SetAudioDevices (HR, AudiDeviceInfo); }  

We are using SIPEk () for SIP stack. Basically we only use a callback representative from the SDK for audio content, is there any other problem with loops like this kind of audio feedback? Either with RIL Audio or SIPE? Any suggestions?

Thanks in advance!
