Hi,

I have something not working anymore. I can’t dial to my dyndns domain frm internal.

Feb 7 01:30:57 WARNING[20091] chan_sip.c: No such host: MYDOMAIN.homedns.org Feb 7 01:30:57 NOTICE[20091] app_dial.c: Unable to create channel of type 'SIP' (cause 3 - No route to destination) Feb 7 01:30:57 VERBOSE[20091] logger.c: == Everyone is busy/congested at this time (1:0/0/1)

and :

# host MYDOMAIN.homedns.org MYDOMAIN.homedns.org has address 80.XXX.YYY.ZZZ

And i’m sure it worked before.
How it possible ?
Is it a new feature in 1.2.4 version that we can’t call ourself ?

[b]Solution : I had to [u]remove srvlookup=yes[/u] from sip.conf, and it works fine now. I don't know what it is used for, and why I added it... [/b]

you haven’t put this behind a different firewall have you ? it’s sounds like a common anti-spoofing policy that prevents NAT’d machines from connecting to an external address that’s port-forwarded.

you could always just add an entry to your local hosts file to see if that gets around it.

The asterisk server in on the firewall, same PC.

And, adding in /etc/hosts can’t change anything, because, this server has its DNS server too, which correctly resolve the dyndns host.

That’s asterisk which doesn’t want it.
