list of Enterprise extensions and their mappings to extensions at each site. For example, an enterprise with 4-

digit dialing might have the following information in its databases.

Site Account Name Account Password Current address Site Description

allworx1 ****** 66.64.219.38:5060 New York City office

allworx2 ********* 64.129.42.33:5060 Atlanta office

allworx3 ***** 129.116.21.193:5060 San Diego office

The current address is the IP Address and SIP Protocol port of the Allworx

server. This can be static or

updated through periodic SIP Registration. The Enterprise extensions could be configured as follows:

Enterprise Extension User User Extension Site

1234 John Doe 108 allworx1

1452 Larry Tate 111 allworx1

4689 Fred Jones 108 allworx2

5999 Jane Smith 177 allworx3

For example, John Doe in New York City dials 84689 to reach Fred Jones. The SIP INVITE is sent to the

central hub with a URI of <sip:4689@centralHubAddress>. The Central Hub validates the sender’s

credentials and looks up 4689 in its databases. It composes an INVITE with a URI of

<sip:108@64.129.42.33:5060> and sends it to allworx2. Fred Jones answers the phone and the call is

established.

Shortly after, John Doe dials 81452 to reach Larry Tate. The SIP INVITE is sent to the central hub with a URI

of <sip:1452@centralHubAddress>. The Central Hub validates the sender’s credentials and looks up 1452 in

its databases. The recipient is on the same server as the sender (allworx1), so the hub responds with a 300

Redirect with a Contact header URI of <sip:111@66.64.219.38:5060>. The Allworx

server (allworx1) then

initiates a call to extension 111. Larry Tate answers the phone and the call is established.

7.3.3 How to Set Up Enterprise Dialing

1. Go to the Phone System / Outside Lines page.

2. Either Add New SIP Proxy or, if it exists, Modify SIP Proxy that is the target for the Central Hub.

3. Check Proxy is an Enterprise Server under Call Route to indicate the SIP Server is an Enterprise central

server.
