Hi Benny and others, When I test the latest PJSUA on a PC (Window XP) with talking to a softphone on a PocketPC (WinMobile 6), I have the following problems. ? 1. If PocketPC calls the PJSUA, I can hear from the PocketPC side but not the PJSUA side. (I use SIP calls. To answer the call, I type "a" and then 222 for the code.) After a short period, the connection is closed and get the msg: "pjsua_app.c Call 0 is DISCONNECTED [reason=408 (request Time out)]" ? Do I need to configure PJSUA to hear the audio? How can I increase the Time out period? (I already used the "V" command to increase the audio volume.) ? 2. If PJSUA calls the PocketPC, both sides can not hear the audio. I got the error messages like "strm00E0378C RTP recv() error Connection reset by peer <WSAECONNRESET> [err:130054]" But the PocketPC receives the call. ? If I use another softphone instead of PJSUA on the PC, above two problems do not appear. Thanks your helps in advance. Paul -------------- next part -------------- An HTML attachment was scrubbed...
