We have a problem in that calls are dropped after 15 minutes (on both internal and out going calls, incoming calls do not seem to have that limit) How do we fix it?

This is the version on that PBX

  • You may gain some insight from viewing the console output after bumping up the debug and verbose levels.

    You will probably resolve this by using tcpdump to capture packets and wireshark to see what’s happening.

    I had a problem with a similar description that was resolved by refusing SIP session timers.

  • I’ve seen calls drop after 10 mins when SIP session timers are enabled.
    Try setting them to refuse in sip.conf.

  • I had a similar issue and i set a timeout which fixed the issue SIP/trunk/ ${EXTEN},2160000,t

    We only had this on one of our providers the rest we havent had the issue

  • Set session-timers=refuse in sip.conf and do a sip reload. We had this problem with a handful of devices and this ultimately stopped the issue.

    Thanks, Derek B.

  • The solution that fixed our problem was to Edit the sip_general_additional.conf file by adding the line “session-timers=refuse”
    Thank you to each one who gave suggestions.
