[asterisk-users] Asterisk freezes when DNS not working: a BUG??

[Giorgio Incantalupo]

Hi,
I'm using Asterisk 1.2.9.1. I have big problem with SIP VoIP providers 
registrations: Asterisk freezes when it cannot (re-)register with VoIP 
provider (registration timeout). The problem is related to DNS names 
resolution: if DNS server is very slow to respond Asterisk stops every 
activity (no zap or restart commands on CLI). The bad news is VoIP 
providers usually do not give their IP so I cannot use it.

Is there anybody who had a problem like this?

TIA
