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
Peer User/ANR Call ID Format Hold Last Message Expiry Peer
182.154.16.150 xxxxxxxx 483333333333335 (nothing) No <guest>

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

Could potentially be a firewall issue, can you make an inbound call straight after an outbound?

I'll see if we can have a look at your registrations attempts and see if I can spot anything odd.

PM me your details - account number or phone number would be suitable.

Do you have firewall rules restricting your SIP traffic and if so did you update these when WxC changed their IP addresses?

Slaps open palmed hand against own face!!!

I have a rule on the internal SonicWall that got updated. But I forgot to update the rule on the Juniper SRX I've got on the outside!
I feel like such a doofuss!

Thanks guys!

So it turned out to be a couple of things.
1/ external rule had not been updated.
2/ external NAT entry had not been updated.

Thanks for the pointers guys. I started looking at it late last night and couldn't see the forest for the trees!
