[cisco-voip] Redirecting Diversion Header Delivery - Outbound SIP trunk call forward

[Joel Perez]

Hey Bill,

I had to take care of this same issue and did it two ways.
First way is not as nice and neat but it works. I did it using the below
commands on the GW:

voice class sip-profiles 44
 request INVITE sip-header Diversion modify "(2...)@" "954713\1@"  ------>
matches the 4 digit internal extensions in SIP header and replaces it with
the npa-nxx of the DID allowed on that sip trunk.

dial-peer voice 101 voip  ----> Dial peer to sip provider
voice-class sip profiles 44


Other way was to create a separate partition/CSS just for Cfwd. On the RL I
left the Calling party transform mask empty, left the "Use Calling
party/external mask" as default.
On the RG in "outbound calls" I left the "Calling party selection" as
originator.
On the SIp trunk in "outbound calls" i also left the  "Calling party
selection" as originator and the rest as default. This was on cucm 7.1 with
CUBE 12.4.22T I think.

Hope that helps somewhat.

Joel P.
