Not from CUCM, you'd need to do it in IPCC as you said.  Set the CFUR  
to a new script that can read in the forwarding station, call out to  
the branch, input the desired DTMF digits, then complete the  
transfer.   If you are forwarding in any way into the first IVR you  
will need the redirect out of that IVR to reset the forwarding  
information so that the new script will see the correct phone as the  
forwarding station/original called party and not the dummy DN that  
redirected to the first IVR.

Hello all.

I'm trying to backup a voip connection with a branch via PSTN. The  
branch has SRST configured and the phones are switching to branch  
router (2821) properly if there's no connection to CUCM at central  
office.

The branch has several analog lines (FXO), all of them are served by  
an IVR (tcl AA).

I've configured "call forward unregistered" on all the branch ipphones  
to those analog PSTN numbers.

The problem is that the users need to dial the extension TWICE. They  
dial the extension, if there's no connection, call forward brings them  
to the branch's IVR via PSTN, which asks to dial the extension AGAIN.

Is there's a way to automaticaly outpulse DTMF digits in connected  
state? (BTW, there's a call consult transfer function in IPCCE, which  
has the "outpulse DTMF digits" option)

Thank you.

P.S.

All ipphones are SCCP.

P.P.S

Sorry for possible double posting, not sure if the first message have  
reached the server.
