Chapter 5. How To Conﬁgure Advanced SIP

In the Forward To table, you deﬁne where calls should be forwarded. This is used in the

Dial Plan table below.

In this case, the calls should be forwarded to your SIP operator account that was deﬁned

before. You select the account under Account.

Enter the IP address of the IP-PBX in the Replacement URI ﬁeld. This will make the

Telecommuting Module replace the domain part in the incoming call with this IP address.

The username part of the URI will be kept.

At last, you combine these deﬁnitions in the Dial Plan table. Select the operator and the

Request-URI, and forward to the PBX.

Finally, go to the Save/Load Conﬁguration page under Administration and apply the new

settings by pressing Apply conﬁguration.

How To Use Multiple SIP Operators or

IP-PBXs 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 description is targeted for multiple operators or PBXs where the Telecommuting Mod-

ule selects destination based on the called number and the caller.

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

has been installed.
