[Freeswitch-users] Rewriting Remote Party ID

[rod]

Dear list,

I'd like to rewrite the number in the Remote Party ID header and only in 
this header.

ex: I'd like to prefix the caller  ID with a prefix code (000 in this 
example) in the  RPID header :

        From: Anonymous<sip:anonymous at anonymous.invalid>;tag=1208367
        Remote-Party-ID: 
<sip:123456 at 10.10.10.10:5062;user=phone>;privacy=full;screen=yes;party=calling

should become:
        From: Anonymous<sip:anonymous at anonymous.invalid>;tag=1208367
        Remote-Party-ID: 
<sip:000123456 at 10.10.10.10:5062;user=phone>;privacy=full;screen=yes;party=calling

But the From field should remain unchanged.

And how to strip this prefix:
        From: Anonymous<sip:anonymous at anonymous.invalid>;tag=1208367
        Remote-Party-ID: 
<sip:000123456 at 10.10.10.10:5062;user=phone>;privacy=full;screen=yes;party=calling

should become:
        From: Anonymous<sip:anonymous at anonymous.invalid>;tag=1208367
        Remote-Party-ID: 
<sip:123456 at 10.10.10.10:5062;user=phone>;privacy=full;screen=yes;party=calling


regards.
