Cisco CVP SIP headers modification

[Igor Filatov]

Hi guys.

Does anyone has experience in SIP headers modification on CVP (10.5 and higher)?

In ICM script it is possible to add data into header, like "Refer-To~sub~>~?Call-Info=TEST DATA>" in Call.SIPHeader.

But I need to change Referred-By header. By default CVP uses this format: <Referred-By><sip:CVP@X.X.X.X:5060></Referred-By> where X.X.X.X is CVP address.

I need to have <Referred-By><44xxxxxxxxxx@X.X.X.X:5060></Referred-By> with original called number.

When I set it in ICM script it just doesn't work, in CVP log I can see:

[INBOUND]Trying to set headers in REFER request with these operations: Referred-By: <44xxxxxxxxxx@X.X.X.X:5060>

But the sip message is not affected, it is still <Referred-By><sip:CVP@X.X.X.X:5060>

All right, I sorted it out.

It is need to use mod syntax: "Referred-By~mod~<44xxxxxxxxxx@x.x.x.x:5060>"
