Hello list<br><br>I've just noticed a problem in our Freeswitch (version 1.0.head (git-3fd7b8f 2011-02-13 18-04-17 -0500)) when it stays in the middle of a g729 negotiated call. I haven't found information to this particular problem previous posts to the list.<br>
<br>The dialplan is trivial, the only relevant line is a bridge to the destination ip address:<br><action application="bridge" data="sofia/internal/${cld_number}@${destip}"/><br>The call goes through but the quality is very bad becuse half of the packets are not relayed from the FS to the originating ip. From the logs:<br>

<br>I've tried to explicitly set ptime at 20ms at switch.conf -although it's not necessary afaik-. Has any one experienced this same issue?<br><br>Thanks in advance..<br><br>Regards<br><br>
