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.
