Change UPDATE's FROM field to match caller id (RPID) with SIP normalization script

We have CUCM 9.1 connected internally to Mitel (MCD 6.0) via SIP.  Transferred calls between the two systems don't display the correct caller ID on Mitel sets.  This is because Mitel uses the FROM field in UPDATE messages for caller ID on sets display.  CUCM never changes the FROM field.  It is always the originating name and number.  Wondering if a SIP Normalization script can be written to change the FROM field in UPDATE messages to match the RPID and or PAI caller ID info.

Hi Rick,

It is possible to trigger transparent pass through  of information on from one SIP dialog (representing 1 of the call legs)
to the other.   Currently, transparency is limited to INVITE dialogs between 2 SIP Trunks. If SIP Line is involved, transparency is not supported. SUBSCRIBE dialogs, PUBLISH, out-of-dialog REFER, out-of-dialog unsolicited NOTIFY are not supported, and MESSAGE are not supported.

Please refer Supported Features for more details.

Thanks and Regards,

Geevarghese
