Multiple users with the same work number - fouling up UM Name Lookups RRS feed

  • Question

  • Background: We are using Lync 2013 and Exchange 2013, both on premise. Our users in the same building all share a common LineURI with a unique extension (i.e. +12085551212;ext=23105). Our UM automated attendant shares the same LineURI scheme (+12085551212;ext=23000). 

    Here is my issue: Some of our users are putting their work number and extension in the Active Directory Telephone Number field in the format "(208) 555-1212 ext 23105). When they do this it fouls up the UM name lookup process when they use a PSTN number to call out and back in to another extension in our dial plan. The missed call notification or voicemail now shows the name of one of the users that input their own telephone number, such as "Joe Smith"; it no longer shows the name of the building, such as "Pocatello High School".

    My question: Is there any way to specify an override that all numbers coming in to UM from +12085551212 resolve to a specific active directory object, or even specify a name that it will resolve to? Open to any suggestions.

    Thanks in advance.

  • I appear to have solved my own issue. I supplied the following values in the msExchUMCallingLineIDs field:

    +12085551212

    12085551212

    2085551212

    That solved the issue. UM appears to be searching those values before it moves on the the Telephone Number field.
