I have an inbound DID range 214-981-9900 thru 9999 to an AT&T SIP trunking to SM. I need to correctly program the CM trunk-group incoming call treatment to change the 9900 to 9999 number range to 7900 to 7999 on our dial plan.
AT&T is sending in 10 digits and I am not sure how many digits to delete and insert in the incoming call treatment table in the CM trunk-group.
