EC500 and carrier long distance codes

[systemsdude]

Hello All,
I have a PRI that the carrier prompts the users for code if calls were considered long distance. Is there a way to add the carrier code to the cell number or some where in the CM to allow EC500 operation without asking for the trunk code.
Now if outsiders call the extension the carrier is blocking it from following the EC500 by asking for the trunk code. All ideas welcome.

For the station you are trying to use do the following

change off-pbx-telephone station-mapping xxxx
For Trunk Selection you may have it set as ARS, but you might try selecting a trunk that doesn't require account codes for this extensions EC500 programming.
