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
Thanks for any response.

Your option is to use UAC module. If you rewrite the From: header directly you can have interop problems.

Thanks a lot.
Based in your experience (and other people's experience here): is it normal a SIP_PSTN provider just support callerid in the "From" header and doesn't support "RPID" or "P-Asserted-Identity"? That it occurs in "real life"?
I assume Nortel CS2000 allows "RPID" or "P-Asserted-Identity" (not sure but I suppose it), but maybe the provider limites it and just allows "From"?
Best regards.

You will find all kind of behaviors out there... some carriers support rpid/pai, some don't... some softswitches/gateways will support them, some not or will depend on the firmware version loaded in the boxes.
Yes, it's not funny but real life ;)

RPID never made it out of draft. We've been doing the UAC_from rewrites with no problems. We still use RPID with our cisco media GWs but plan to switch to P-Asserted-Identity at some point.
One large US ITSP insists on us rewriting the To header which is really broken:-) We don't use them. /a

Thanks both fot the help.

I hope don't find this need !!
Thanks again.

i don't have good enough net access to check, but does pai header also support controlling of display of calling number like rpid does with its privacy parameter? if not, then it cannot be used as a replacement of rpid header
-- juha
Juha,
I believe this is handled in RFC3325: Private Extensions to the Session Initiation Protocol (SIP) for Asserted Identity within Trusted Networks, RFC4497: Interworking between the Session Initiation Protocol (SIP) and QSIG, and RFC3323: A Privacy Mechanism for the Session Initiation Protocol (SIP) which is the "Privacy" header.
RFC4497 section 9 says: "A gateway MAY implement the P-Asserted-Identity header in accordance with [14]. If a gateway implements the P-Asserted-Identity header, it SHALL also implement the Privacy header in accordance with [13]. If a gateway does not implement the P-Asserted-Identity header, it MAY implement the Privacy header."
[13] is RFC3323 [14] is RFC3325
/a

Juha,
PAI/PPI normally goes with Privacy header (see RFC 3325), so it's a proper replacement for RPID.

I once had an issue with signaling network and user provided CLI to the PSTN. IIRC the conclusion was to put the user provided CLI into From: and the network provided into PAI.

Afortunatelly the provider has just confirmed me that they support both headers RPID and PAI, yeah! :)
