External Phone Number Mask

I am running CUCM 7.1 with CUBE to my SIP trunk provider. I setup an external

phone number mask from my house cordless phone (connected through ATA) so that it shows the house number. That works great when I dial anybody from the house phone. To enable someone to get a hold of me when I am out, I setup the line to forward to my cell phone after a certain amount of no rings. The problem is, the caller ID number displayed on my cell phone with the call is forwarded is the first seven digits of my house phone followed by the last four digits of the original caller. In other words, if my phone number is 555-555-1234, when the incoming caller is forwarded to my cell phone, it reads 555-555-0000 (whereas 000 is the last 4 of the caller that got forwarded).

I have checked my route patterns as well as the gateway configuration for anything that resembles a wild card to append the last four to the number, but nothing. Anyone have any ideas? Thanks for anyhelp

Make sure to check for Calling Party Transformation CSS set either on the trunk or on the device pool of the trunk if the use device pool calling party CSS is checked.
