[asterisk-users] IAX2 woes

[--[ UxBoD ]--]

Hello all, 

I attempted to make a couple of outbound calls this morning and always got the busy tone. I checked the Asterisk console and was greeted with: 

[Dec 29 11:29:22] WARNING[12039]: app_dial.c:2218 dial_exec_full: Unable to create channel of type 'IAX2' (cause 20 - Unknown) 
== Everyone is busy/congested at this time (1:0/0/1) 

I proceeded to restart Asterisk and dialed the same number again and it worked without fault. What could cause this type of error and is there any way to auto-remediate when it does arise ? 

voip*CLI> core show version 
Asterisk 10.0.0 built by root @ voip.my.server on a x86_64 running Linux on 2011-12-19 16:16:46 UTC

Thanks, Phil
