Hi all, <br><br>I'm testing video calls between XLite and 3g handsets using Asterisk 1.4.21.1 as PBX. I've got almost everything working except for an stranger behavior with the video.<br><br>The escenary is the asterisk installed with an public IP adress and the XLite softphone running on a PC behind a router (private IP). Well; I register the XLite client in Asterisk and originate a call between the two endpoints. The result is that:<br>
<br>- audio works fine in both directions<br>- 3G -> XLite video works perfectly too<br>- XLite -> 3G video has very good image quality BUT in slow motion, what makes the video more and more delayed <br><br>I haven't seen nothing special in both the SIP and PRI debug (except the <i>rtp.c:1286 ast_rtp_read: Unknown RTP codec 126 received</i> that I think doesn't matter, for what I've seen around). I have configured XLite with only the h263p video codec, and my sip.conf is:<br>
<br><br><font size="1">[general]<br>context=default ; Default context for incoming calls<br>allowoverlap=no ; Disable overlap dialing support. (Default is yes)<br>bindport=5060 ; UDP Port to bind to (SIP standard port is 5060)<br>
bindaddr=X.X.X.X ; asterisk IP address )<br>srvlookup=yes ; Enable DNS SRV lookups on outbound calls<br>disallow=all ; First disallow all codecs<br>allow=sln<br>allow=h263p<br>allow=amr<br>allow=g711a<br>
allow=alaw<br>allow=gsm<br>dtmfmode = rfc2833 ; Set default dtmfmode for sending DTMF. Default: rfc2833<br>videosupport=yes ; Turn on support for SIP video. <br>maxcallbitrate=64 ; Maximum bitrate for video calls (default 384 kb/s)<br>
<br>[img4]<br>type=friend<br>username=img4<br>secret=img4<br>host=dynamic<br>nat=yes<br>disallow=all<br>allow=h263p<br>allow=alaw<br>allow=amr<br>allow=gsm<br>allow=raw<br>maxcallbitrate=60</font><br><br>Does anybody know the reason of this inapropiate "slow motion"? Is there a solutions or is some kind of problem/incompatibility between Asterisk and XLite? Something that could be resolved with the non-free version of XLite?<br>
<br>Thank in advance,<br><br>Torino<br>
