[asterisk-users] register suddenly fails

[Norbert Zawodsky]

Hi everybody,

I've got a very strange problem:

As far as I remember I didn't change anything on my Asterisk side. I
have 2 SIP providers to which I can place outbound calls.

Today I noticed that outbound calls to provider "inode" fail (and
inbound from this provider too). On the CLI I get every 20 seconds
following messages:

Nov  9 20:01:07 NOTICE[952]: chan_sip.c:5422 sip_reg_timeout:    --

DNS lookup works:

root at asterina:~# ping voip.inode.at

Since I am sure that I didn't change anything within the last week, I
called inode support. But they said, that they didn't change anything
either.
Next I tried was a 'SIP RELOAD' which produced following output:

asterina*CLI> sip reload

asterina*CLI>

Now, what makes me wonder ist the first line after the reload which says
"Unable to lookup 'h.  }....."

Anybody of you got any idea ??
