Running a small cloud-based FreePBX 15 system for several years. For past several days, one of the extensions can no longer place calls either to outside phones nor other extensions.
Looking at logs when I try to make an internal call, it appears it’s showing as “unknown”:
411363[2022-03-24 15:18:13] VERBOSE[C-0000000a] pbx.c: Executing [[email protected]:1] NoOp(“PJSIP/anonymous-0000000e”, “Received incoming SIP connection from unknown peer to 301”) in new stack
And then being dropped:
411375[2022-03-24 15:18:13] VERBOSE[C-0000000a] pbx.c: Executing [[email protected]:7] Log(“PJSIP/anonymous-0000000e”, "WARNING,“Rejecting unknown SIP connection from 174.xx.yyy.zz:5060"”) in new stack
(note: 174.xx.yyy.zz is my WAN IP and is configured as Trusted in the FreePBX firewall. Also note that other extensions can dial without issues)
I’ve also noticed when dialing (internal or external) that I do hear a dial tone, but after that no audio whatsover - no messages, busy signals, errors etc.
As I mentioned above, inbound calls to this extension (internal and external, it has a DID routing directly) continue to work without any issues.
Wondering how this happened (I don’t believe I did anything in FreePBX that would cause this behavior) and how to fix it.
Thanks for any help and insights!
