MGCP - Need to modify Calling ID on outbound calls

[kylebrogers]

Here is the situation.  We have an MGCP gateway tied to our CUCM cluster (7.1.3).  When a call comes into the PRI on the gateway, I append a 9 to the inbound number.  This is so that users can go to their "missed calls" and simply hit DIAL rather than having to EDIT DIAL and add the 9 themselves.  This is working fine.

The problem comes when user A forwards their desk phone (deskA) to their cell phone (cellA).  When User B calls deskA from their cell (cellB), the call comes in the gateway and has a 9 appended to the beginning of their cell phone number.  When deskA forwards this call back out the PRI to cellA, cellA sees 9<cellB> as the phone number.  Is there a way in MGCP to do some sort of "forward-digit" outbound so that I can make it only forward the right-most 10 digits?

Try this:

Make a new partition..lets call it Call_Fwd_PT

Make a new route pattern... 9.@, or 9 and whatever you use for outbound calls, and place in the Call_Fwd_PT partition

In the route pattern configuration, under outbound calls, put the calling party transform mask as XXXXXXXXXX (10-digits), this should strip the leading 9 on the calling party number

Make a new calling search space, lets call it Call_Fwd_CSS

Put the Call_Fwd_PT in the calling search space

Assign the Call_Fwd_CSS as the call forward all calling search space on phone A.

Let me know if that works.

Earlier, I tried putting the XXXXXXXXXX in the 9.@ route pattern that the phone was hitting as it forwarded calls and it didn't make a difference.  I also tried XXXXX just to see if it was even looking at that field and it still gave me 9+10-digit.  I think because the call is a forwarded call, the forwarding options on the phones (the check boxes at the very bottom) override the settings on the the dial peer.

Is there an equivalent to a translation rule that I could use with the MGCP gateway to affect the outbound Calling Party ID?

Try using calling party transformation CSS at the device>>gateway>>PRI page on the CUCM. You will need to create Calling party transformation mask on the CUCM. Check this link to help you out
