Advanced SIP

3Com VCX IP Telecommuting Module provides a lot of SIP possibilities. In this chapter,

some advanced SIP setups will be presented with step-by-step instructions for the conﬁgu-

ration.

How To Use Your SIP Operator Account Via

3Com VCX IP Telecommuting Module

This is how to conﬁgure your Telecommuting Module to register at your SIP operator, and

to use that SIP account for your local users.

This feature is only available when the Advanced SIP Routing or the SIP Trunking module

has been installed.

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.

Outgoing Calls

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.
