Multiple AVPP Multiple AVPP environments are those which have more than one AVPP in the same subnet in order to
accommodate larger systems and higher call capacity.
In a system comprised of multiple AVPPs using an IP protocol, a master AVPP must be identified. The
master AVPP server must have a static IP address. The wireless phones and the other AVPPs locate
the master by using a static IP address, DHCP, or DNS.
The loss of a non-master AVPP does not significantly affect the operation of the remaining AVPPs.
However, the loss of the master AVPP results in a loss of all communication between all of the AVPPs.
This also means that the loss of the master AVPP results in the loss of all active calls and wireless
phones cannot check-in until communication with the master is re-established.
Note
10, 20 and 100 AVPPs will not operate together in a network. The network must consist of all 10,
all 20 or all 100 AVPPs.
In the IP PBX environment, AVPPs provide both the connection or "gateway" to the IP PBX for the
wireless phones and the "timing" function for active calls. This "gateway" function is distributed across
the AVPPs.
The number of active AVPPs is determined dynamically. Whenever AVPPs are added to or removed
from the system, the distribution of "timing" function for active calls, as well as the "gateway" function, is
affected.
A gatekeeper is required in certain H.323 protocol systems. Currently, a gatekeeper is not supported.
