Re: [Asterisk-java-users] Asterisk/AGI response problem

[Brett S. <bs...@no...>]

Are you certain that its not a DNS issue.
If the asterisk server has periodically having trouble resolving dns 
names to ip addresses then you can experience the sort of delays you are 
talking about.
You can eliminate this as a possibility by using an IP address in the 
dial plan. Of course if you are already using an IP address then this is 
less likely to be the case. However be aware that if the asterisk-java 
libraries is doing any DNS or reverse DNS lookups before it passes the 
call to you then again you can experience the problem.
