1. Introduction

"MSS trunk" is an inner protocol in MSS. It can support relaying SIP signal and media streams. In another way, MSS uses a simple STUN protocol for "MSS trunk"! With MSS, it is very easy to breaking ISP barriers.

Following sections describes how to configure "MSS trunk" in a demo network.

2. Demo network

network topology

Holly and Gilson in the same company and they hope to establish VOIP communication with each other. Holly lives in A.E and Gilson lives in U.S.A. But in A.E, SIP messages are blocked or changed by ISP, so it is hard to establish a VOIP connection.

In this scenario, Holly and Gilson have following requirements:

Then, we deploy MSS trunk to fit these requirements. In our deployment, two miniSIPServer, MSS1 and MSS2, are deployed in U.S.A and A.E. In above figure, it looks like that they will be connected directly by MSS trunk. In fact, MSS trunk is based on UDP and can be transported on Internet.

In the network, MSS1 is in A.E and its domain name is "holly.myvoipapp.com" and MSS2 is in U.S.A and its domain name is "gilson.myvoipapp.com".

In Holly's office, the users' number has the prefix '1', such as 100, 101 and so on. In Gilson's office, the users' number has the prefix '2', such as 200,201 and so on. In this document, we don't mention how to register local SIP phone to MSS and please refer to MSS' manual document.

3. Configuration

Note that if you modified the item which is marked with '*', you should restart MSS to enable it.

3.2 Dial plan

Click menu "Dial plan / Analyze called number" to configure a new recordto route calls. In following figure, we describe how to configure it to route call from Gilson to Holly since Holly's prefix is "1".
