Agreed. This seems very similar to our other discussion:

Take a look at SIP profile manipulation/normalization

If you're on 15.1(3)T it introduced conditional SIP profiles which let
you manipulate one header based on the contents of another,  most useful
for when you need to route on the TO/FROM field when the SP can't or
won't re-write the request-uri.

Hi everyone,

 

This is kinda a continuation on the original email I sent through titled
"SIP Header - SIP Privacy: ID"

 

Scenario is

 

SCCP Phone -> CUCM 8.5 -> CUBE -> Telco

 

The Telco wants to see the Privacy set to ID and the "From" Field
showing a number that is "authorised" 

 

I can set the Privacy to "ID" on the CUCM which rewrites the "From" to
From: Anonymous - This is blocked as the "From" is "Unauthorised" (This
is seen on the CUBE)

 

Is there any way of matching the "From" field and re-writing it so that
it contains a valid number that is "authorised"? The devices I have
access to are CUBE(IOS 15.x) / CUCM (8.5) / ASR.

 

Thanks for any help with this one...

 

Cheers,

 

Johnny
