<div dir="ltr">Hello! I'm using the latest opensips with latest rtpproxy :<br><br>Basic version: 20040107<br>Extension 20050322: Support for multiple RTP streams and MOH<br>Extension 20060704: Support for extra parameter in the V command<br>Extension 20071116: Support for RTP re-packetization<br>Extension 20071218: Support for forking (copying) RTP stream<br>Extension 20080403: Support for RTP statistics querying<br>Extension 20081102: Support for setting codecs in the update/lookup command<br>Extension 20081224: Support for session timeout notifications<br>Extension 20090810: Support for automatic bridging<br><br>i
did setup the secure tls connection between clients in the opensips, it
uses the client certificate verification. But the interaction with rtpproxy is getting messed up somehow. I'm
using the blink softphone to test on. So i have 2 accounts: bob and
alex. When i do <b>call</b> <b>bob</b> <b>from</b> <b>alex</b> i get this kind of behaviour in the <b>bob's softphone</b>:<br><img src="cid:ii_i63wh3hr0_14b842b40226eeab" height="37" width="404"><br>So it hangs on "starting media", but in the same time the actual
connection is established, me and my partner can hear each other and we
can talk perfectly, so i assume the actual stream is allright. It hangs
for exactly 15 seconds then we get:<br><img src="cid:ii_i63wj7qq1_14b842cc331ba96a" height="23" width="404"><br><br><p style="text-align:left;clear:both"><b>"media stream timed out while starting" in the bob's softphone</b>.</p><p style="text-align:left;clear:both"> <b>On the alex softphone side</b>:</p><p style="text-align:left;clear:both"><img src="cid:ii_i63wk7972_14b842d76c419fe7" height="26" width="404"><br><br></p><p style="text-align:left;clear:both"> "call ended by remote". <br></p><p style="text-align:left;clear:both">The
icon indicating that rtp stream is encrypted is not shown on bob's side,
but the stream is working. I tried to disable tls, and use plain tcp,
and it's working fine without tls, call is not getting stuck and automatically terminate. <br></p><p style="text-align:left;clear:both">My rtpproxy is running like so:</p><p style="text-align:left;clear:both">rtpproxy -u rtpproxy -s udp:localhost:12221</p><p style="text-align:left;clear:both">And my opensips config is generated by osipconfig utility (i didn't modify the routes at all) see attached opensips.cfg<br></p><p style="text-align:left;clear:both">I looked up the syslog for rtpproxy entries, apparently there is no entries from rtpproxy or opensips with any error, other than</p><p style="text-align:left;clear:both">Feb 13 04:00:24 user /usr/local/sbin/opensips[17535]: ERROR:rtpproxy:force_rtp_proxy: Unable to parse body</p><p style="text-align:left;clear:both">Feb 13 04:00:22 user /usr/local/sbin/opensips[17535]: DBG:tm:matching_3261: RFC3261 transaction matching failed<br></p>
I hope someone can help me to solve this problem, i'am hanging on this
for a week. If necessary i can post the syslog and blink softphone sip traces, of our test conversation. Maybe the problem is with ACK? <br></div>
