asterisk users - May 2011 - asterisk fails when DNS or internet fails

Hi,

Would just like to inquire why asterisk fails to send calls in / out
when the DNS is failing
or when the server with asterisk has no internet. Ip phones are
connected via IP address and i am using an FXO card, so even if
internet fails i should still be able to make calls thru the fxo. but
that is not the case.

i am using the latest asterisk 1.4 and dahdi. any help would truly be
appreciated. thank you.

Regards,
Ron

Hi,

it is a known problem, one of the worst. To avoid it:

- do not use urls, only ip addresses in sip.conf

or put your urls inside /etc/hosts (is what I do especially sip 
providers urls)

or install a dns-cache on your pbx (maybe the best solution)
