Hi, I’ve installed ELASTIX (Free PBX) a while back for a small business, incoming calls are working without any issues, outgoing calls are successfully connected and you are able to hear and talk (person on the other end can hear and talk as well), however, after 50 seconds (ranges from 40-90 sec) audio seizes, neither party can hear nor talk, call will stay connected for over 24 minutes as long as neither party hangs up, once one party hangs up/disconnects the call, the call is ended. My VOIP Service Provider is Vitelity, they’ve been giving me the run around for quite some time, they now are telling me that it’s related to my router, that the ports are possibly not configured properly or “nat=yes” needs to be configured, they say it’s related to the RTP packets being dropped and not transferred properly back to the FREE PBX server.
I double checked my settings on the router and outbound trunk settings, and they are configured accordingly, all incoming and outgoing UDP and TCP 5060-5061, 10000-20000 ports are set to forward to the VOIP (Free PBX) server, the trunk settings is configured as such…
context=from-trunk ; (this could be ext-did or from-pstn as well)
Any help would be greatly appreciated!
Thanks in advance…
