[Serusers] sip address problem

[Oliver Zilken]

Hi,

I have a strange problem with my ser router, which already worked
correctly since a few weeks:

I cannot dial any address without the prefix "sip:" and the suffix
"@mydomain.com" anymore. 
For example, when I just type in "echo" instead of
"sip:echo at mydomain.com", I get an "not found" error.
When I dial a no. through my ISDNGW, i.e. "1004" instead of
"sip:1004 at mydomain.com", I get an "Interplanetary Toodle Noodle" error.

Does anyone know a reason for this ?

Oliver
