Preparing for a New Installation / Preparing the Vocera SIP Telephony Gateway |
You can install multiple Vocera SIP Telephony Gateway servers —also called a telephony server array—at each site.
By installing an array of telephony servers at a site, you can take advantage of the following high availability features:
Generally, all telephony servers at a site will use the same PBX. However, they could use different PBXs as long as all PBXs have the same configuration for the trunks to the telephony servers and the same capabilities for off-PBX dialing (for example, tie lines).
Telephony servers in an array do not communicate with each other. Instead, the telephony servers respond to requests from the Vocera Voice Server. All communication with telephony servers is handled by the Vocera Voice Server.
