Things Suddendtly stop working

By things I mean, my sip trunks, outbound and inbound, my phones etc.

The server has been working perfectly for well over a year then on monday everything stopped. The first thing I did was check the logs and the only interesting thing in there is this line.

[2014-03-12 10:28:00] NOTICE[3905]: chan_sip.c:13316 sip_reg_timeout: – Registration for ‘[email protected]’ timed out, trying again (Attempt #391)
[2014-03-12 10:28:00] WARNING[3905]: chan_sip.c:3696 retrans_pkt: Retransmission timeout reached on transmission [email protected] for seqno 492 (Critical Request) – See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions
Packet timed out after 180697ms with no response

Thats an incoming trunk line.

Next here is a phone trying to register, with tcpdump I see the data come in.10:34:40.443760 IP 192.168.91.100.sip > 208.70.56.61.sip: SIP, length: 749
10:34:44.445839 IP 192.168.91.100.sip > xx.xx.56.61.sip: SIP, length: 749
10:34:48.446004 IP 192.168.91.100.sip > xx.xx.56.61.sip: SIP, length: 749

I get nothing in the logs, no errors, nothing. And I turned up debuging and verbosity to the max.

It seemed like a firewall issue local on the machine so I disabled all firewalls same symptoms.

Running FreePBX 2.10.1.16

Any ideas on what to try next?
