Hi Sergio, Make sure your dispatcher probing parameters are set correctly. (reply codes as well).
And if it happens again you can catch OPTIONS traffic with sngrep "CSeq: [0-9]+ OPTIONS" and see what happens on this level. Whether Kamailio does send pings, whether replies from gw are the same as expected, etc. Regards, On Wed, Sep 16, 2020 at 5:55 PM David Villasmil < [email protected]> wrote: > Hello > > I would start by looking at the logs when that happens.
