Outbound calls stop working after 3 hours

Hello all, we have an odd issue where sip calls and inbound calls work okay, however after 3 hours outbound calls stop.
to rule out all modules, we have tried to do a full reload from the asterisk console, the issue only resolves when we restart the actual service.
The error we see when the problem starts is as follows:

asterisk/messages:[Feb 10 09:12:09] WARNING[8130] chan_iax2.c: Max retries exceeded to host (providers ip) on IAX2/iax-out-10113 (type = 6, subclass = 1, ts=5, seqno=0)
./asterisk/messages:[Feb 10 09:16:11] WARNING[8129] chan_iax2.c: Max retries exceeded to host (providers ip) on IAX2/iax-out-11553 (type = 6, subclass = 1, ts=10, seqno=0)
./asterisk/messages:[Feb 10 09:17:18] WARNING[8129] chan_iax2.c: Max retries exceeded to host (providers ip) on IAX2/iax-out-7544 (type = 6, subclass = 1, ts=8, seqno=0)

any ideas?
Thanks

Look for dynamic NAT, or firewall, rules timing out, and also for DHCP not properly configured to reallocate the same address on a renewal. Basically, I think your issue will be in a router.

Thanks for the input, will do some digging.
