Hola Iñaki,

Hi, I will connect my OpenSer with a Nortel (SIP to PSTN gateway) for incoming/outgoings call to/from PSTN.

I have a doubt: if an OpenSer user (200@mydomain.org) receives an incoming call from gateway, could he REFER the call to 201@mydomain.org?

This is: do ITSP gateways allow REFER to SIP users subcribers to my OpenSer? I understand they could not accept REFER's to PSTN number because accounting issues (gateway UAC receving a REFER and calling to PSTN?).

As with rpid/pai, some carriers will accept and others don't.

At least it's nice to know that the possibility may exist :)
