Hi,
My inbound calls have stopped working (OpenVFX).
It's been happening for about a month now, but I've been very lazy and have just gotten around to looking at the issue. 

One thing I've noticed is that I frequently get the message "[2014-07-02 23:52:04] NOTICE[2999]: chan_sip.c:15135 sip_reg_timeout:    -- Registration for 'xxxxxxxx@pan.wxnz.net' timed out, trying again (Attempt #51)"

Out bound calls are perfectly fine BTW.

There haven't been any changes to the environment (other than a SonicWall firmware update I did a while ago).

I can ping pan.wxnz.net (182.154.16.150) fine.

Other information:
CLI> sip show channels

CLI> sip show peers
Name/username Host Dyn Forcerport Comedia ACL Port Status Description
VFX/abcdefghijklmnopqr 182.154.16.150 Yes Yes 5060 OK (21 ms)

I'm on an Orcon connection (for what it's worth).

Any ideas anyone?


Cheers
