Setting up a tenor PA system for Lync 2013

 

This setup requires quite a bit of  configuration. However, since I had the experience I wanted to share as much as I was able to learn about the process. The Idea of setting a PA for Lync is the ability to Page to any location in the company.

The flow goes like this: The user at the corporate office picks up the phone. The user dials a 4 digit extension. The call goes to the Lync Dial plan. The Dial Plan normalizes the number (as a Lync analog device) and sends the number to the Gateway at the local office. The local office Gateway can send the call to a Valcom type device that accepts the call, using an RJ11 connection. However, the way we are setting this up today is to use Lync. In this case, the call will go from the Gateway, to the embeded SBA, and to a Sonus Tenor device. The Sonus Analog Gateway send the call to Valcom.  The Valcom is plugged into any existing PA system, by placing the audio out to the PA speaker system.

Let me recap; Lync Phone, Lync Dial Plan, Local office Sonus Gateway, Sonus Tenor, Valcom device, Legacy PA system. I don’t have every step to perform this implementation, but I do have the guidelines of the resources to be able to put a design together. That does seem like allot of work. And it is. I am only scratching the surface, but this article attempts to define the basics of how this is done.

Items you will be required to have Include the following:

  • A fully built Lync Organization
  • A local office Gateway/SBA a Sonus UX2000 will do
  • a Sonus Tenor analog gateway
  • Sonus Tenor Gateway Manager
  • a PA device like a Valcom v-2006A
  • a speaker system in the ceiling
  • a Lync phone to make the call (or a Lync client)

Once you have these all set up you can begin. First register at the Sonus portal.  This will allow you to obtain user guides for their products. In particular, use guide for the gateway you will be using. This document should also contain the the setup for the Tenor gateway. From the NET product documentation hub, you can download the UX 3.0 PDF. That was used in the setup to which I am wringing about. 

In Lync Server, Begin by adding an analog device by using a Lync power shell command similar to:

New-CsAnalogDevice -LineUri tel:+16001 -DisplayName “Building 14 Receptionist” -RegistrarPool redmond-Cs-001.litwareinc.com -AnalogFax $False -Gateway 192.168.0.240 -OU “ou=Telecommunications,dc=litwareinc,dc=com”

This command allows a call to go from 5556001 to 192.168.0.240 and is registered to the Redmond pool.

Next, create a unique dial plan and  trunk configuration to route the call to the correct line URI. For example, your dial plan may normalize the number to +16001. Next, the call is going to the gateway.

 

In the Sonus User guide, Review the setup instructions for to add a gateway transformation that will forward the call to the Tenor (figure 1).

You will need to make a Lync to Tenor transformation and a Lync Sip to ISDN call routing table. This is in the documentation how to set up. Set aside at least 2 hours to get through with the setup of this portion of project. There are several steps. On page 1032 of the document “Using Tenor as an Analog Device in a Lync SBC SBA Deployment”, you will find the steps. In order to accomplish this, you will need to install the Tenor Gateway Manager. This is a disk that comes with the Tenor, and is used on the LAN to connect to any Tenor. There is no web interface so do not throw the disk away when you open the box.

Once complete, the setup of the Valcom device completes the setup. Valcom v=2006 is a device I picked at random, but essentially it takes an off hook from the Tenor and also has an audio out for a PA system. I will leave you with the FAQ on the device and it does answer allot of questions.

I will point out a few gotchas on the setup. First check the get-cstrunkconfiguration service:pstngateway:fqdn.domain.com. Review this against the settings in the trunk configuration versus the dial plan. did you normalize to +1, or did you remove the 1? since the number is going from pool, gateway,tenor, and valcom it is likely this will be an issue. the gateway may expect 4 digits. it may be best to simply remove the + from the trunk configuration from the gateway.

check get-csanalogdevice. The LineURI needs match the dial plan.

If you are not using a Tenor device, the Sonus gateway can be configured to send the call to the Valcom, This is hearsay at this point. I did not set it up this way.

Setting up the Tenor, the instructions say to set the numbers tables. However, it is not possible until you go to the gateway below and enable the tables. See figure 2.

Finally, The basic setup for the Sonus can be accomplished with a wizard, Choose tools from the top menu bar and select launch Launch Basic setup Wizard (Figure 3)

In conclusion, There are several complexities you may run into and I did not cover them all. But I hope you have a basic understanding on how to find the information you need and have a little better understanding on how to set up a remote PA system with Lync 2013.
