hi, for some reason recently when i try to make calls using a SIP endpoint (passing them along to asterisk) i get a SIP 100 message ("trying-your call is important to us") instead of the call being passed on. The endpoint is registering with SER (according to serctl). I can't find any documentation on this - i think it's because the nat configuration is screwed up on the endpoint.
What does this message mean? anyone have any links or pointers?
apologies for the basic question, yair
