I have a number of 2851 utilizing the IOS gatekeeper. These all point to a 2851 which is acting as a directory gatekeeper. From the directory gatekeeper down our dialing plan is 10 digits in length. We also are part of a bigger organization in which our directory gatekeeper is neighbored/peered to their gatekeeper. In order for someone from the outside organization to dial into us they have a 6 digit prefix they add to the E164. How can I get our directory gatekeeper to strip the 6 digit prefix from the dial string and forward the remaining 10 digits to the appropriate gatekeeper below it?
