Hello ser users,

I wish all sip message are handle by ser.

phone1 -------------------------- | ser+mediaproxy|------internet phone2 --------------------------

In order to send all sip messages via ser I set outbound sip proxy (ser/public ip) for sip clients.

However ser don't route invite message for other domains.Why?
