Connecting to a Site to Use Its Telephony Server

When you use the "Connect to Site" command to connect to another Vocera site, the telephony server and PBX that are used when you make telephone calls depends on whether you are dialing an extension or an outside number:

For example, say your company has sites in Los Angeles and New York. If your home site is Los Angeles, you can say the command "Connect to New York" to connect to that site. Once you are connected, you can then say "Dial extension 3145". The Vocera Server uses the telephony server for that site to dial the local extension.

If the site that you connect to does not have its own Vocera SIP Telephony Gateway and instead shares the telephony server at another site, then calls are made through the shared telephony server. When you set up shared telephony for a site, you can specify the prefix of the dial string used to place calls through a tie line to the site. This tie line prefix allows you to dial extensions at the remote site even though the site does not have its own Vocera SIP Telephony Gateway Server.
