T20P Remove Country Code from Call Log

[nalinna]

Our VOIP sevrer does not allow country codes to be dialed prior to dialing out, and our T20P phones automatically append the country code to the call log. This is obviously frustrating while trying to dial out directly from the call log.

Anyone know if there's a way to remove the leading country code from the call log? Or if there's a way to replace any number that matches 1[0-9][0-9][0-9]-[0-9][0-9][0-9]-[0-9][0-9][0-9][0-9] with [0-9][0-9][0-9]-[0-9][0-9][0-9]-[0-9][0-9][0-9][0-9] (essentially cancelling the 1 out without forbidding the call)?
