13.3.3 Enterprise Dialing Feature
The Enterprise Dialing feature enables a third party SIP server to be the central hub for
calls between multiple sites that have Allworx servers. This provides a centralized phone
book and administrative service for the entire VoIP network.
13.3.4 Allworx Enterprise Client
Configure each Allworx server as an enterprise client and direct inter-office calls to the
central hub. The system creates an SIP Proxy for the central hub with the call routing set
to Proxy is an enterprise server. The Enterprise Dialing rule (Phone System > Dial Plan
page) is set to a service group that contains just the SIP Proxy entry for the central hub
server. The number of digits to collect/send is set to cover the entire enterprise.
The Allworx dial plan uses an ‘8’ prefix
1
to indicate forwarding the dialed number to the
Enterprise Server. For example, dialing 81234 sends a SIP INVITE with a URI of
<sip:1234@centralHubServer> to the Enterprise Server.
13.3.5 Central Hub / Enterprise Server
The central hub is a SIP proxy server that accepts incoming INVITEs from the Allworx
servers, determines the final destination for the request, and forwards the request to the
Allworx destination. It maintains an active list of Enterprise extensions and the mappings
to extensions at each site. For example, an enterprise with four-digit dialing might have
the following information in its databases.
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. Configure the Enterprise
1. Extensions may vary per system. If using a non-default Internal Dial Plan, consult the My
Allworx Manager > Phone Functions tab to determine what extensions to use for the
corresponding feature.
