Rewriting is known to cause interop issues, it is safer to store PSTN
number in user profile and append it in a special-purpose header field,
either Remote-Party-ID or P-Asserted-Identity. An example for the
former is to be found in [PSTN] route of ser.cfg, see
http://cvs.berlios.de/cgi-bin/viewcvs.cgi/ser/sip_router/etc/ser.cfg?rev=HE…
You just need to re-"printf" the header field properly if your terminating
gateway supports P-asserted-identity instead.

you need to talk to the ITSP. Are you doing a
uac_replace_from? Some SPs ignore the RPID as it never became a standard.

Thanks for the comment.
No, what I tried so far was to append rpid header to all frames that goes
toward PSTN gateway.
What would be the best way to rewrite "From:" header using
uac_replace_from? Rewriting both deiplay and url or just display portion?

Hi, a Happy New Year to all.
Looking for help to get our caller-id working for outging PSTN calls.
We have 3rd party PSTN gateway service and all our callee gets the
gateway
phone number as CID for all of our sip calls to PSTN.
I had implemented so far sip-rpid, remote-party-id, through avp,
append_rpid_hf() and confirmed rpid headers on all pstn outgoing frames.
However, callee only see the SP's PSTN gateways number as incoming
caller-id. Is there other way of implementing caller-id for sip calls
before I bring the subject to PSTN service providor? Or is it most
likely
SP's policy setup?
Thanks in advnace.
