okay, so ALL your users are registering to asterisk...is that correct.
Correct via ser as outbound sip proxy
If so the problem is howto accept users from behind a NAT into asterisk, or am I confusing things further.
the problem is in contact field. when user agents send register we have in sip hf Contact sip:user@privateip So asterisk store this AOR and try to contact agent via nat box instead of SER
If the above are true, where is SER in this, or are users hitting SER and you are sending the REGISTER from ser into asterisk.
SER is an outbound sip proxy which handle IM presence nat
