Far out! I have found the problem and it all due to the fact that I don't know
what I am doing (
When I do tcpdump on eth0 (WAN), every call I make e.g. even extension to
extension does this:
09:28:14.684997 IP 172.17.17.200.54004 > 172.17.17.1.domain: 60192+ AAAA?
3999-IBCBuild-CM1.ipcsolutions.local. (54)
09:28:14.685599 IP 172.17.17.1.domain > 172.17.17.200.54004: 60192 NXDomain
0/0/0 (54)
09:28:14.701505 IP 172.17.17.200.52348 > 172.17.17.1.domain: 26730+ AAAA?
3999-IBCBuild-CM1.ipcsolutions.local. (54)
09:28:14.701989 IP 172.17.17.1.domain > 172.17.17.200.52348: 26730 NXDomain
0/0/0 (54)
Why is it trying to resolve my local host?
When I check local domain it fixes this problem but is this the best practice?
Sorry Im a little confused!

Subject: Re: [Astlinux-users] Delay after Asterisk Dial when no DNS
Hi Michael,
It is my understanding that chan_sip trunks only does DNS lookups at (asterisk)
startup unless you enable ... dnsmgr.conf -> enable=yes . Possibly registers
always do DNS lookups, not certain.
As long as local DNS entries are in your hosts file (Network tab -> DNS
Forwarder & DHCP Server: { Configure DNS Hosts } it should work, I would guess.
In the old days, I recall running Asterisk 1.2 and 1.4 on single core boxes
like the PC Engines WRAP and Soekris net4801, and Asterisk DNS lookups were
blocking and could *totally* lock-up a system when the WAN connection went
down. I have not seen than behavior, personally, in quite some time.
Multi-core and dnsmasq helps.
