[asterisk-users] DNS lookups failing for SIP register

[Alistair Cunningham]

It seems that Asterisk 1.2.9.1 has a problem doing DNS lookups for SIP 
"register =>" lines. Lookups on the same machine using "host" or "ping" 
work, but Asterisk gives:

No such host: example.com
Probably a DNS error for registration to 12345 at example.com, trying 
REGISTER again (after 20 seconds)

(Domain replaced with example.com)

Putting an entry in /etc/hosts, or using an IP address in the register 
line, works.

I also think, but cannot be sure, that this system worked with older 
versions of Asterisk in the 1.2.3 to 1.2.5 era.

Has anyone else seen this?
