[Users] RE: [Serusers] open letter

Hello open(ser) asterisk users Here is what i expect to do : Asterisk: registrar with public ip port=5050 open(ser): outbound proxy with public ip port=5060 Asterisk don't support IM and presence so i want to use SER because of it's a good proxy: I want user agents behind nat send registration to asterisk because of it's an ipbx :-) Look at this diagram when user agent behind nat send REGISTER to ser the contact field in sip header has a private address which one is forward to asterisk for registration. When user agent are registered in asterisk AOR is sip:user@private ip so asterisk query "sip:user@private" behind nat (not possible). How a session between two user agents behind nat could keep in the path |register | | register | agent1 asterisk| |ser/nat box | | | 200 OK | | 200 OK | agent2 One box --------------------------- | ---------------- | | | asterisk pbx | | | ---------------- | | || | | ---------- ---------- | | SER |====|NAT box |==== private network | ---------- ---------- --------------------------- Send me your questions if you don't understand what i expect to do .
