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.
