OpenSER Asterisk Incoming Calls No Longer Ring


I do not know what occured but within the last two days, three of my extensions no longer ring my phones (Polycoms and analog-ata) when receiving an incoming call from Zap/1 but my zyxel rings fine. I have no idea what transpired to make it stop working as before, as I have not changed anything. [OpenSER/Asterisk Integration - public IP]

Here is a printout of the asterisk console:

– Executing Dial(“Zap/1-1”, “SIP/|15|m”) in new stack
– parse_srv: SRV mapped to host, port 5063
– Called
– parse_srv: SRV mapped to host, port 5062

Also, when * is in idle mode: the asterisk consoles prints this over and over:

-- parse_srv: SRV mapped to host, port 5062
-- parse_srv: SRV mapped to host, port 5061

And another situation that recently occured during this same period, when dialing one of my extensions via SIP only, there is no ring on the phone itself but in the * console I see this instead:

– Executing Dial(“Local/51112@default-2953,2”, “SIP/|10|r”) in new stack
– parse_srv: SRV mapped to host, port 5064
– Called
– Local/51112@default-2953,1 is ringing
– Nobody picked up in 10000 ms
– Executing Playback(“SIP/51112-08624820”, “vm-nobodyavail”) in new stack
– Playing ‘vm-nobodyavail’ (language ‘en’)
== Spawn extension (default, 51112, 1) exited non-zero on ‘Local/51112@default-2953,2’
– Executing VoiceMail(“SIP/51112-08624820”, “51112@default”) in new stack
– Playing ‘vm-intro’ (language ‘en’)

…as if it’s just being relayed right back to asterisk immediately. On the phone itself (Polycom 500SIP), i will receive a quick ring and that’s it and upon pick up nothing. However, it used to be when dialing this extensions, there would be no activity on the console until the phone had already rang about 8 times with no response, like the other extensions currently still do.

Any ideas?
