Enabling Enteprise Voice RRS feed

  • Question

  • Hi,

     If we enable Enterprise Voice and configure users phone numbers(Work,Home) etc and then try to dial a Lync Users Number can the Lync Server be configured to select a route that does not go to PSTN gateway. Isn't the PSTN gateway/IP-PBX needed only when you are trying to dial out or trying to call a user who is registered with another PBX?For ex: user A has the work number configured as 9507 and user B is configured as 9543. Now when the user A dials 9543 call should hit the user B without going through PSTN gateway because the user B is in Lync.

  • When a number is dialed from a Lync/OCS client, the Lync server performs a process known as Reverse Number Lookup (RNL). This process attempts to match the dialed and normalized number to a user or contact's msRTCSIP-Line Active Directory attribute, otherwise known as the TEL URI. If a match is found, the call is routed internally via the user or contact's SIP URI and will not route to the PSTN gateway. If a match is not found by the RNL process, the number is routed via the configured Voice Policy to a PSTN gateway.

  • By just setting the tel uri it doesn't automatically display it anywhere.  Home, work, office numbers are pulled from the telephonenumber, homephone and mobile AD attributes if they are populated and in E.164 format, or normalize to E.164 using the Company_Phone_Number_Normalization_Rules.txt file.

  • Correct, it will be treated as a PC to PC call using SRTP with RTAudio i believe.

  • Thanks Jamie, I tried configuring the TEL uri and see if I can make calls. It worked. But does this configured number for a user show up in the profile of Lync User. To which field does this tel uri field will be applied..home, work, office? If only TEL uri is specified how will the other users know of the contact number?
