Toshiba Release 4.0 manual Connecting two Servers using IP Gateways

Connecting two Servers using IP Gateways ________________

You can configure Strata CS’s integrated Internet gateway to connect two Strata CS Servers over the Internet or a private IP network (sometimes called a tie-line connection). Doing this allows users on one Server to make calls as if they were on the other Server.

When two Strata CS Servers are properly configured, users can do the following:

nPlace calls to extensions on the remote Server. In addition to calling extensions, users can dial # to log in and check remote voice mailboxes, or 411 for the remote Server’s dial-by-name directory.

n

n

Place external phone calls through the remote Server. Users can

call remote phone numbers as if they were local phone numbers, such as calling directory assistance in another city.

Place outbound Centrex/PBX calls through the remote Server. Users can dial remote Centrex/PBX extensions as if they were local, such as extensions on a legacy PBX system connected to the remote Server.

nUnify two Servers into a single user environment. By creating users of the type IP Gateway on each Server, you can make all users appear to be of the user type User. Users on each Server can dial each other directly or select extensions for call forwarding and routing lists regardless of whether they are local (of the user type User) or remote. Local and remote users appear together in the Client’s Users view, Place Call To dialog box, and other user lists.

Note: Assembling larger networks of more than two Strata CS Servers is technically possible, but if a call is transferred to a remote Server, and then transferred back to the original Server, two IP trunks are used on each Server. Because the call is originating and ending on the same Server, this setup can waste resources and bandwidth.

Placing calls involving a remote Strata CS Server

To make an IP Gateway call, users must choose the appropriate dialing service when placing the call, either by dialing the access code over the phone, or by selecting it in the Client. See “Creating IP Gateway dialing services” on page 13-13.

By creating users of the type IP Gateway, you can also enable users to dial remote extensions directly, without dialing an access code, or place calls to them from the Client. See “Creating Gateway users to unify two Strata CS Servers” on

page 13-17.
