[cisco-voip] Rewriting the "From" in a SIP header

[Nicholas Samios]

Take a look at SIP profile manipulation/normalization
http://www.cisco.com/en/US/products/sw/voicesw/ps5640/products_configuration_example09186a0080982499.shtml

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.

Subject: [cisco-voip] Rewriting the "From" in a SIP header

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
