Asterisk Bug with DNS Alias?

Hello,

the provider easybell has the registrars:

sip,easybell.de
and
sip.voipcs.de running.

If you ping them, you'll will see that it's the same IP.

now the funny thing:
sip.easybell.de - is not registering
sip.voipcs.de works.

I tried it with other hardware and it seems an "Asterisk only" Problem.

Maybe some Asti Geek can help?

Cheers

easy

RE: Asterisk Bug with DNS Alias?

Based on the DNS records of the two FQDNs you mentioned, only the sip.voipcs.de has a direct relationship with the 62.53.230.92 IP. The sip.easybell.de points to the sip.voipcs.de and the sip.voipcs.de points to the 62.53.230.92 IP.
