a. In the 'Proxy Address' fields, configure two proxy servers for redundancy. If the
SBA application fails (at the branch office), the PSTN Gateway switches over to
the Mediation Server located at the datacenter.
♦ Index 1: IP address or FQDN of the Mediation Server running on the
Mediant 1000B SBA (configured in Section 15.1.4 on page 154).
♦ Index 2: IP address or FQDN of the Mediation Server running at the
datacenter.
Note: If you configured the Mediation Server address as an FQDN, ensure that you
configure the DNS server (see Section 15.1.2 on page 153).
b. In the 'Transport Type' drop-down list, select the Transport Type (TLS or TCP) for
these proxies. For more information on TLS and TCP Transport Type
configuration, see Section 15.1 on page 151.
c. From the 'Enable Proxy Keep Alive' drop-down list, select Using Options to
discover whether a particular Mediation Server in the cluster is available.
d. From the 'Is Proxy Hot Swap' drop-down list, select Yes. If there is no response
from the first Mediation Server after a user-defined number of retransmissions,
the INVITE message is sent to the redundant Mediation Server. The number of
retransmissions is configured by the Number of RTX Before Hot-Swap parameter
in the 'Proxy & Registration' page (see Step 1 on page 145).
