Table 10-23: Redundant Genesys Server - Parameters
Parameter Description
Redundant Proxy Mode From the dropdown, select Simultaneously; you're now in Dual
Registration mode; when in this mode, the value of the parameter
'Retransmission Timer T1' is taken from the configuration file parameter
'voip/signalling/sip/redundant_proxy/dual_reg/t1' rather than from the
'Retransmission Timer T1' parameter (see Table 5-8 for more
information about this parameter).
Secondary Proxy
Address
Provide the IP address of the redundant proxy; the phone then registers
on both servers from the outset, instead of transitioning from one to
another.

Configuration of the T1 retransmission timer is only relevant when in dual registration mode,
i.e., after configuring a redundant Genesys server, as shown in the previous section.
