Summary:                    Asterisk Loses gateway and chansip stops
Description: 
I have seen this issue over many asterisk versions. If an asterisk machine
has a IAX trunk or SIP trunk and the internet drops out then the PBX
basically stops. This is an issue because it makes it impossible for PBX to
drop back to ISDN.

---------------------------------------------------------------------- 
On the basic symptoms, you should have provided deadlock debugging
information - core show locks and an unoptimised backtrace (needs thread
debugging and no optimisation compile time options).

However, my guess is that this is a configuration problem, namely that DNS
requrests are not produceing a destination unchreachable ICMP response or a
prompt DNS failure response.
