The simplest single site deployment scenario has one Vocera Voice Server connected to one telephony gateway using one PBX.
This scenario does not take advantage of any high availability features, such as redundancy, scalability, and load balancing.

To add high availability to a single site Vocera system, an array of telephony gateways can be installed, and two SIP trunks can be used to provide failover support. This scenario provides redundancy, scalability, and load balancing. The Vocera Voice Server handles outbound load balancing by automatically allocating calls to the least busy telephony gateway. The PBX handles inbound load balancing.
