Description
Adds an "Aastra-Line:" header to the SIP
REGISTER messages sent from the phone to
the call server, where the value is the line
number that is being registered.
For more information about this parameter,
see Chapter 6, the section,
Line Number in REGISTER Messages"
page 6-5.
The time, in seconds, that the IP phone uses
to send periodic re-INVITE requests to keep a
session alive. The proxy uses these re-INVITE
requests to maintain the status' of the
connected sessions. See RFC4028 for details.
Default is 0.
For more information, see Chapter 4,
"Advanced SIP Settings (optional)"
page 4-84.
These timers are SIP transaction layer timers
defined in RFC 3261. Timer 1 is an estimate,
in milliseconds, of the round-trip time (RTT).
Timer 2 represents the amount of time, in
milliseconds, a non-INVITE server transaction
takes to respond to a request.
For more information, see Chapter 4,
"Advanced SIP Settings (optional)"
page 4-84.
The amount of time, in milliseconds that the
phone allows the callserver (registrar/proxy) to
respond to SIP messages that it sends. If the
phone does not receive a response in the
amount of time designated for this parameter,
the phone assumes the message has timed
out.
For more information, see Chapter 4,
"Advanced SIP Settings (optional)"
