Vega Gateway Lync Configuration Guide
- Kelli Higdon
Overview
This document will guide you through the process of configuring Vega series of Gateway’s to work with Microsoft Lync Server 2013.
Introduction
Vega Gateway Lync Configuration Guide provides detailed information about the configuration requirements in Vega series of Gateways (Vega 100G, Vega 200G, Vega 400G and Vega 800G) to deploy this in a Lync environment.
A typical deployment connects PSTN/Mobile Network to Vega Gateway on one side using Vega T1/E1 interface and Lync Server on the other side using Vega LAN interface with SIP as a control protocol.
Vega Configurations
Quick configuration
Run “Quick Config” on Vega GUI
On “Basic Config” tab select country. The default country setting is “UK”.
Move to “VoIP” tab of “Quick Config”.
Enter “SIP Domain” field with the domain where the Lync server 2013 is running.

Click on “Expert Config > LAN/WAN”.
Configure a unique name for Vega Gateway on “Hostname” field and “Submit” the configuration.
NOTE: A DNS record should be added in DNS server on the Domain. Lync server would need to resolve this name to contact Vega Gateway.
On the same page “Expert Config > LAN/WAN”, scroll down till “DNS Parameters”
Enter “Static DNS Servers” field with DNS server IP running in the Domain and “Submit”
NOTE: Vega Gateway would be using this DNS sever to resolve mediation server IP address.
SIP configuration
Click on “Expert Config > SIP”.
Enter “Local SIP Port” field with port number Vega SIP would like to listen on.
NOTE: The same port should be configured in “trunk configuration” on Lync Server as Vega Gateway port.
On the same page “Expert Config > SIP”, under “SIP Profiles” click on “Modify” link and enter into “SIP > SIP Profile 1” configuration page.
Enter “Local Domain” field with the domain name Vega gateway and Lync Server is associated with.

Now we need to make some adjustments on the Codec Configuration to avoid offering codecs not needed to establish a call with Lync Mediation Server.
Let's reduce the codec offering to just G.711 and T.38. Remember from the previous points that we are using Capability Set 2-Voice+T38
Click on Page “Expert Config > Media
You will notice all 7 codecs are selected by default on the Capability Set 2.
Click on Modify and lets reduce to codecs 2, 3 and 5
Click on "Submit"
Click on "Apply"
Click on “Save” to save the configurations
Click on “Reboot System”
