Thanks Nathan.  That is a big help.  Maybe I can finally see what is really happening.

It doesn't address your actual issue - but for the pcap - as long as you can respond in a reasonable timeframe for the hit, you can use the tcpdump file rotation options "-C size -W count" to just set up a capture that will rotate through files. It'll create a lot of capture, but it will only keep the last N files.

Subject: [Freeswitch-users] Occasional Dropped call at 30 seconds

Hi all,

 

I have a problem with one client where the call is fine and they can talk for almost exactly 30 seconds, then the log says originating phone (of FS) hung up.  This only happens like 1% to 5% of the time.

 

The phones are Mitel 6867i and 6865i which must use TCP not UDP.  The firewall is a $#!#&* SonicWall.  I am 99% convinced it is the firewall.  It happened once on a Cisco phone using UDP so I increased the firewall UDP timeout.  I already have keep-alive set to 30 seconds.  It has not recurred on UDP phones since.

 

Any ideas on something to do to Mitel config or SonicWall that might prevent a drop after 30 seconds? 

 

I have considered PCAP, but with so few occurrences I am worried about PCAP size before I get a “hit.”

 

Thanks,

Sean
