Lync 2010, Problems dialing international numbers. RRS feed

  • Question

  • Hello, 

    I have a Lync 2010 enterprise server. I'm unable to make international calls on Lync. The problem is when i try to dial an international number that has more than 10 digits, Lync cuts off any additional digits and only sends 10 digit to the PSTN gateway and thus the call fails. If I dial an international number that only has 10 digits then the calls is successful because will send the complete 10 digits to the PSTN Gateway. By the way I'm located in the US which uses 10 digit numbers for local calls. For some reason Lync is limiting all calls I make to 10 digits.

    I believe I have all steps configured correctly: DialPlan, VoicePolicy, PSTNUsage, and Route. When I use the Test Voice Routing tool on Lync 2010 Console to check my normalization rules for international calling everything looks good.

    Can you guys help figure out what am I missing? Thanks!

  • If the test tool shows that the digits are being normalized properly, that should rule out the dial plan.  But, how do you know that only 10 digits are sent to the PSTN gateway?  Logging on the gateway?  Check the trunk configuration as well to make sure there are no called number rules in there that may be interfering.

  • Hi Eightbitsshort,

    Agree with Anthony.

    Which product did you use for the Gateway? Microsoft recommends to use verified gateway, please refer to the following
    https://technet.microsoft.com/en-us/office/dn788945.aspx

    Please refer to the document below check the trunk configuration
    https://technet.microsoft.com/en-us/library/gg398170(v=ocs.14).aspx

    Moreover, please double check and make sure your dial plan is correct.

    I was logging in to the gateway, that's how I could see that Lync was only sending 10 digits to the gateway.

    You were right, the issue was in the Trunk Configuration. I had a normalization rule that was stripping away digits after the 10th digit.
