CUCM and CUC Phone menu

Hi all.
There is a bunch of CUCM and CUC. The CUC implements an electronic menu for incoming calls with several submenus including redirection to real managers. So, when a call is forwarded to a manager, there is not a single dial tone until the manager picks up the phone, that is, before the client is answered, he hears absolute silence. Help with advice on where the problem might be

I would guess that Ringback messaging is not flowing back to the caller. Can you post a SIP trace of the incoming call to the SBC to CUCM to CUC and back to CUCM?
