      The FreeSWITCH instance sometimes "forgets" to send a SIP RE-INVITE (we use session timers to periodically send RE-INVITEs on all our SIP channels) which then results in the remote party dropping the SIP channel by sending a SIP BYE to the FreeSWITCH. By sometimes I mean that this happens maybe once for several thousands of RE-INVITEs. I scanned the FreeSWITCH log files but could not find any reason why the FreeSWITCH did not send these RE-INVITEs.

      We used the following settings:
      <param name="enable-timer" value="true"/>
      <param name="minimum-session-expires" value="90"/>
      <param name="session-timeout" value="90"/>

      In the attached log file "re-invite_freeswitch.log" one can see the last RE-INVITES and the resulting BYE in the lines:

      101343: send 1083 bytes to udp/[]:5060 at 22:14:56.635618:
         INVITE sip:994023150001@ SIP/2.0

      106734: send 1083 bytes to udp/[]:5060 at 22:15:40.657420:
         INVITE sip:994023150001@ SIP/2.0

      112802: send 1083 bytes to udp/[]:5060 at 22:16:29.676978:
         INVITE sip:994023150001@ SIP/2.0

      124212: recv 419 bytes from udp/[]:5060 at 22:18:00.455498:
         BYE sip:mod_sofia@ SIP/2.0

      By the way, we patched the FreesSWITCH sources to be able to send SIP INFO messages with a proprietary XML content type.

      By increasing the frequency of SIP INFO messages, we could reproduce the problem within minutes.
