Gateway to Gateway

Gateway to Gateway
A call may be placed from one Xcelerator IP to another Xcelerator IP via the Call Routing
Table. The call Routing Table allows the user to make a direct call to an extension in
another Xcelerator IP. It also allows the user to share the PSTN or IP Trunks in another
Xcelerator IP to make an outside call.

IP Trunk

Xcelerator IP can register up to 8 SIP Uplink Servers. The extensions may make a call to
the users of the Uplink Servers, or any user in the world through the Uplink Servers.

Line Group Assignment

The Xcelerator IP can assign each PSTN/IP line to a specific Line Group. Each line can be
assigned to only one Line Group. The Line group assignment is used for Line pool access.
Both PSTN lines and IP lines can be programmed into the same Line Group. The line
access sequence will be dependant upon the access priority.

Make an Outside Call

The Xcelerator IP provides three methods to make an outside call:
The extension user dials the phone number directly. Xcelerator IP automatically
routes the outgoing call using the least expensive line via Call Routing Table.
The extension user dials a Line number or a Line Group number first. After hearing
dial tone, the user dials the phone number.
The extension user presses a Line Key first. After hearing dial tone, the user dials
the phone number.

Message Waiting Indication

When a message is left in the called party voice mailbox, the IP2007 LCD will display new
voice mail information, and its voice mail LCD will flash accordingly.
