Administrator's Manual A. Configuring Phones in Server-Specific Deployments
Version 2.2.8 297 400HD Series IP Phones
Table 53-18: 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 17-6 for more
information about this parameter).
Secondary Proxy
Address
Provide the IP address of the redundant proxy; the IP phone then
registers on both servers from the outset, instead of transitioning from
one to another.
A.3.17.1 Configuring Retransmission Timer T1 Using the Configuration File
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.
 Configuring Retransmission Timer T1 using the Configuration File:
1. Open the Configuration File page in the Web interface (Management tab > Manual
Update > Configuration File).
2. Configure the capability using the table below as reference.
Table A-19: Retransmission Timer T1 - Parameter
Parameter Description

server is configured. Allows quicker
retransmission of SIP messages than the Web
interface parameter 'Transmission Timer T1' and
overrides it if configured (see Table 17-6 for
more information).
Default: 20 milliseconds. Range: 20-200.
