Hello there,
Kia ora,
I'm using a Debian box with Asterisk 1.8.13.1 as a DID-PSTN gateway, so I can receive calls in a DID number and redirect it to my mobile line. It has been working flawlessly for a few months, but I have noticed that some calls were not cut after losing one leg (the one with the DID server), and kept the PSTN leg active until I restarted the server (with the unexpected cost involved in the PSTN call). The relevant extensions.conf line is: exten => 34911234567,1,Dial(SIP/pstn/447123456789) And both DID and PSTN sip accounts have canreinvite=yes, so they can have direct media. I haven't collected any debug log nor any other relevant information. Does anybody know why something like this happens, or how can I cut a call that unexpectedly losed a leg?
Since you are having media go directly the only thing that can be monitored is the signaling of the call itself. This can be accomplished using SIP session timers. There is a section "SIP Session-Timers" in the sip.conf.sample file which has the various configuration options relating to it.
