Chapter 5. How To Configure Advanced SIP

How To Use Your SIP Operator Account and Your IP-PBX Via 3Com VCX IP Telecommuting Module

This is how to configure your Telecommuting Module to forward requests between your SIP operator and your local IP-PBX.

The configuration varies slightly depending on if the operator uses accounts or IP addresses for the authentication.

This feature is only available when the Advanced SIP Routing or the SIP Trunking module has been installed.

Instead of configuring this manually, you can use the 3Com Startup Tool, which can be found at http://www.ingate.com/Startup_Tool.php.

Outgoing Calls

Authentication by Accounts a.k.a SIP Trunk via SIP accounts

Enter your SIP operator account on the Local Registrar page. You enter the username and password from the operator, and select the XF/Register account type. This account type will make the Telecommuting Module register at the SIP operator with the credentials you enter.

Some operators don’t require registration. In this case, select the XF account type instead.

You can select any network in the Register from field, as it is not used for these account types.

For outgoing calls, you have to define when your SIP operator account should be used. Usually, you use this type of account to call to the PSTN network ("ordinary telephones").

On the Dial Plan page, you define what type of calls should be redirected to your SIP operator. First, turn the Dial Plan on.
