I have an MGCP implementation and an E1 implementation and all 8 digits are passed to us. We need to translate this to 5 digits to pass to the phone. We created a translation pattern from all 8 digits to 5 digits, and the call cannot be completed. The error we are seeing from the debugs states: unallocated/unconfigured number. My question is how we translate this number to 5 digits.
