Hi all, Both problems are solved! I followed the steps of "Audio Problem: Unable to hear voice in local speaker" in http://trac.pjsip.org/repos/wiki/audio-problem-local-no-audio#AudioProblem:Unabletohearvoiceinlocalspeaker?. These steps with the debugging features of pjsua are very useful. Thanks Benny and others to document these and others steps. First, I made sure that the speaker worked fine by looping-back the microphone to the speaker as well as playing a wav file. The commands "cl" and "cc"?of pjsua help. Then I found that the PC got very small number of RTP packets using the command "dq". After reading carefully the "Getting Around NAT", I made the following two changes: 1. Run pjsua with "--stun-srv=stun.sjphone.org --no-vad --ip-addr??MyIPAddress --rtp-port 4000", where MyIPAddress is the IP address of my PC such as 192.123.1.456. 2.? Change the Port Range Forward of my wireless router (LinkSys WRT54GLa). After login the router, goto "Applications & Gaming/Port Range Forward", add two items pjsua, 5900, 5900, Both, MyIPAddress, Enable pjsua, 4000, 4100, Both, MyIPAddress, Enable for the fields of?Application, Start, End, Protocol, IP Address and Enable respectively. Then Save Settings. Now, the pjsua can call or answer?the softphone on my PocketPC through a wireless link. It is exciting!

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...
