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?).
Usually it depends on the configuration of the gateway. Thus, I would add some screening of REFER and 3xx to the proxy.
Sorry Klaus, I don't understnad what you mean with "screening of REFER and 3XX to the proxy", could you explain it please?
Thanks a lot.
