I’m having an issue with a Polycom VVX 150, it rnadomly get unregistered for a minute or so.
Until then I was using Linphone or Alcatel Temporis IP 600 with no issues.
I don’t know how to diagnose the issue.
Here is the log :
[2021-04-21 10:34:24] VERBOSE chan_sip.c: Unregistered SIP '704' [2021-04-21 10:34:40] VERBOSE chan_sip.c: Registered SIP '704' at 192.168.21.186:5060 [2021-04-21 10:39:44] NOTICE chan_sip.c: Peer '704' is now UNREACHABLE! Last qualify: 18 [2021-04-21 10:40:40] NOTICE chan_sip.c: Peer '704' is now Reachable. (19ms / 2000ms)
Here is my conf
I managed to reduce the down time by playing with the expire. But I don’t understand the difference between the “Expire” and “Subscription Expire”.
The phone and the FreePBX are in different VLAN but no NAT in between and all ports allowed (for debuging purposes)
Thanks for your help.
