CUCM Not passing through Referred-BY header

Unanswered Question
May 20th, 2010

We have a client using CUCM and Exchange2010 UM.

- Calls comes to CUCM and get routed to Exchange 2010 UM.

- Exchange 2010 sends REFER back CUCM with Refer-TO and 'Referred-BY' headers set.

- CUCM initialtes an INVITE with the service Provider (Final end point), how ever not passing through the 'REFERRED-BY' header.

Does anybody know if thsi is abug in CUCM  or any resolution.

We need the REFERRED-BY header to process the INVITE properly.

Any help is appreciated....

I have this problem too.

I am experiencing this exact problem with Exchange 2010 referring calls to a RightFax server.  The RightFax server isn't getting SMTP information because that is sent in the REFERRED-BY field, which is getting lost by CUCM during the transfer.  I'm running CUCM 8.6(2) and Exchange 2010 SP1.
