Error when making a call RRS feed

  • Question

  • I try to call a phone number of a remote office and I get the following error. "Call unsuccessful. More than one contact is associated with the destination phone number."

    Any thoughts?

  • This could be a situation where multiple user accounts have the same exact phone number entered in their AD account.  This is common when users move locations or if a general main phone number is entered when user accounts are created and their AD attributes aren't updated after being issues a phone extension.

  • Thank you for the quick reply Jeff. I went through AD and changed all the phone numbers before to no avail. I just went back through, rechecked and none of the phone numbers are the same.

  • Any changes you've made in AD will typically take ~24 hours before appearing in Contacts in OC.


    Check this article for more details on the procedure:



    You should also verify that the Line URI field is unique on all EV or RCC enabled users, as that string is how OCS locates a destination number when attempting to 'complete' a call.

  • Jeff,

    I think the resolution to my problem lies in the second link. I have a number of user accounts that have the same phone number in their LINE URI but they all have different extensions. (tel:+15552221212;ext=877). If I deleted the telephone number portion and leave the extension (that is what I did in AD). Could that solve my problem?

    Thank you for the help and the great reference source (PointBridge Blogs).

  • I were faced this issues last week. After checked in the LDAP found there is another user using the same" softphone" number.
    Please check in the AD and re-assign the softphone.
