How to modify contact header on a SIP INVITE at CUBE

Hi all

I have an INVITE coming from CUCM leg at CUBE and then it goes through SP leg being modiied by Sip protocol default's behavior.

CUCM -> CUBE -> SP

The INVITE from the CUCM:

Contact: <sip:490043@23.13.0.251:5060;transport=tcp>;video;audio;isFocus;x-cisco-tip;x-cisco-multiple-screen=3

INVITE sent to provider:

Contact: <sip:490043@192.145.71.XX:5060;transport=tcp>;x-cisco-tip;

------------------------------------------------------------------------------------------------------------------------------------------------

I need copy "x-cisco-multiple-screen=3" from CUCM contact header INVITE and paste on INVITE sent to provider.

I have raised a TAC case for this but no success so far.

This is done in order to overcome a SIP limitation that does not allow use the 3 screens that Cisco Telepresence Endpoint has. The protocol is TIP (Telepresence Interoperability Protocol)

does anyone has faced this situation before?
