    Dears;

    i have LYNC 2010 enterprise voice deployed with call manager direct SIP. also Exchange 2010 SP1 UM installed and configured corectly with LYNC 2010.

    my enviroemnt is like: lync users have 5 digits , PBX are 4 digits. all voice integration is working fine between lync and call manger.

    my problem that when i call AA from pbx or lync client. i hear AA welcome message but when i press pbx extension " four digits" it provide me message that am not permitted to transfer call.

    i have checked that UM certificates are working fine and i have disabled refer to allow calls to be routed from UM to lync users.

    my confguration, that i have created one UM dial plan and its 5 digits SIP secure and have IP gateway for the LYNC front end pool. i have noticed that my AA is not working if its secure VOIP , it should be SIP secure.

    i have tried to created additional UM dial plan, and creating addition UM hunt group to combine the additional dial plan but with no luck. the additional dial plan were telephone extension,unsecured and i have changed UM VOIP secuirty to be Dual .

    how can i solve this issue?

    thanks alot

    Open the AA properties and go to the Dialing Restrictions tab. Make sure that the "allow calls to extensions" box is checked.

    You may also need to define rule groups in the dial plan that the AA is in, and then add them to the Dialing Restrictions tab in the AA.

    Since your UM dial plan is setup for Lync and 5 digits any other length of digits (less or more) would have to be allowed through dialing rule groups.  The would affect users and callers as well as AAs.

    Dears;

    i would like to thank you for you reply.

    i wanna share with you what i have done and what am stucking at,

    to troubleshoot the problem, i have delete everything and created one dial plan with four digits, sip uri, secure sip only. run exchange script and create my auto attendant with five digit extension.

    when i was calling my AA from pbx phone, am hearing the welcome message and when press four digit extension " which is PBX entesnion  "  , AA was telling that it will transfer the call then , it says call cannot be transfered. from lync logging i figured out the call was not normalized since it go through the default lync dial plan, but not my configured dial plan. so i have created the normalization on the default dial plan and confogured the routing. till this i was able to route the call from AA to PBX phones.

    whats my problem is that when calling the AA, and enter five digits " which are lYNC extensions", AA will take only four digits and refuse the last digit. how can i solve this issue  ? another thing when am trying to configure UM for any user, it ask me for extension which is four digits but i need users t have five digits as this is their lync extensions.

    any help

    Your AA is associated with 1 UM dial plan, so I'm assuming it is associated with your 4 digit/sip uri UM dial plan.  You said your Lync extensions are 5 digits, so why isn't your Lync-related UM dial plan configured for 5 digits?

    Hi,

    Here is what ,I understand about the problem.

    1) UM dial plan is 4 digit extension.

    2) Lync Dial plan is 5 digit extension.

    You are calling AA which transfers the call to either 4 digit extension or 5 digit extension.

    As long as you have proper Lync 2010 Dial Plan with a proper normalization rule , calls will be transferred correctly.

    If the user do not pick up the call then , call will be routed to their voice mail which is affected by 4 digit UM dial plan.

    Solution to your problem would be : A norlalization rule in Lync 2010 for 4 digit extension or 5 digit extension which ever applies to your topology.
