Stephan,

line if (uri=="d254196.cs.stir.ac.uk") is wrong.

Operator == means exact match, but your Request-URI will contain more than d254196.cs.stir.ac.uk.

You can use regular expression matching (operator ~=) or better use uri==myself (in this case uncomment line containing alias=...).

Hi,

I am just trying the new ser version from CVS, and I get a too many hops error message when a client tries to register. Any idea? I am running ser on Linux. I have tried both kphone 3.1 and spic 2.?? as user agents. I am sure I must have missed something in my configuration file. I attach the current ser.cfg. thanks,

Stephan
