Hi coders!! Yes, I'm trying to use pjsua for Android: this time I'm referring to the Android branch, and not to the main trunk: this is because I think that pjsua is the most complete pjsip's example application, and I'm trying to port more, as far as many other applications that I've cross compiled seem to work very well!!! I'm running two android clients inside a Local Network by a Netgear Router: the buddy registration goes fine, the starting call also, and also the OpenSLES Driver works very well in the initialization process. By the way, I'm getting some kind of trouble after the sip acceptance call with 200 call from the receiver. I'm using these two commands in two Android rooted devices: $ ./android-pjsua --auto-rec --rec-file=/sdcard/ciao.wav $ ./android-pjsua --auto-play --play-file=/sdcard/au.wav The wav-playing application terminates with a segmentation fault due to this failing assertion: >ACK sip:192.168.0.7:5060 SIP/2.0 >Via: SIP/2.0/UDP 192.168.0.8:5060;rport;branch=z9hG4bKPj6BpWdMTQM8maJW4VeqrzjwsUCuO8MpIN >Max-Forwards: 70 >From: <sip:192.168.0.8>;tag=CnT39R02ibxFUVti2d.SNswxzrwr.86u >To: sip:192.168.0.7;tag=ePlE65PDHud79Ys9S47rKEeL9v5-M6VW >Call-ID: oxU4mf0gjEG-hvbCdU3oCDAB3WL1IcFi >CSeq: 17921 ACK >Content-Length: 0 > > >--end msg-- >00:14:30.678 pjsua_app.c .....Call 0 state changed to CONFIRMED >assertion "cport->rx_buf_count <= cport->rx_buf_cap" failed: file "../src/pjmedia/conference.c", line 1498, function "read_port" >[1] Segmentation fault ./android-pjsua --auto-play --play-file=/sdcard/au.wav You maybe know what this matter is about? Thanks in advance. P.S.: As far as I see that many android question are still answered by this community, I would like too to ask here my questions. I'm posting questions neither because I'm a troll, nor I have a particular interest to confuse people (what would I gain? - Nothing). In fact I'm making here questions because maybe, some of you, have encountered these kind of problems in the past, and so I hope to solve my problems (as an Android and Pjsua's newbie), and also because this is also the best place to ask such questions. Excuse me also for my English, but I'm not a mother-toungue speaker. Thanks again for your support. :-) Monty Python
