Hola Iñaki,
Hi, I need to send SIP traffic from my OpenSer to a Nortel CS2000 (SIP_2_PSTN gateway).
I have a bad new: the provider tells me that they set the callerid with the "From" I send. I've asked them to support "RPID" or "P-Asserted-Identity" headers (still waiting for a reply).
In case I can only use "From" I can modify it with UAC module, but I also know this is very anti-RFC3261 behaviour.
Does anyone know if Nortel CS2000 can use "RPID" or "P-Asserted- Identity" to set the PSTN calling number?
What do you think about changing From header? for example: 200@domain.com -> 00123223223234@IP
Your option is to use UAC module. If you rewrite the From: header directly you can have interop problems.
Saludos JesusR.
