[SR-Users] t_relay dying ?

[Jean Cérien]

Hello
I've tried mhomed = 1 with no luck - not so sure what you mean by default
route, I've added listen = udp:myadsress:5060
I also have auto_aliases=no and alias=myaddress

However, what bugs me is that execution seems to stop INSIDE t_relay and
the info message after the t_relay is not displayed.

I hate to say this, but could this be a bug ?
