Description
Defines how often the phone renews registration with
the proxy. If the proxy responds to a REGISTER with
a lower expires value, the phone renews registration
based on that lower value instead of the configured
value.
If registration fails with an "Expires too brief" error
response, the phone retries with the value specified
in the Min-Expires header of the error.
• In the phone configuration file with
XML(cfg.xml), enter a string in this format:
<Register_Expires_1_
ua="na">3600</Register_Expires_1_>
• In the phone web page, enter a value in seconds
to define how often the phone renews registration
with the proxy.

seconds to 2000000 seconds.

the proxy to answer calls.
