Hi. I need to create the proper normalization rules in Microsoft Lync to enable dial-out to internal four digit extensions on a Cisco Communications Manager 7.1.5 phone system. The numbers in Lync are stored in E.164 format (+1 (262) 555-0123).
I have built normalization rules which strip all but the last four digits of the number to dial, but the call still fails in Lync, with the error that the number is not in service. See the attached file that contains the rule.
Does anyone have experience with bridging a Lync (or OCS) and Cisco voice environments that knows how this should be setup?
