•
Explicit MWI Subscription
If the IP phone has a message waiting subscription with the Service Provider,
a Message Waiting Indicator (MWI) (LED or display icon) tells the user there
is a message on the IP Phone. You can enable and disable MWI by setting this
parameter to 0 (disable) or 1 (enable) in the configuration files or by checking
the box for this field in the Aastra Web UI. Default is disabled.
•
Send MAC Address in REGISTER Message
Adds an "Aastra-Mac:" header to the SIP REGISTER messages sent from the
phone to the call server, where the value is the MAC address of the phone.
•
Send Line Number in REGISTER Message
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.
•
Session Timer
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.
•
Timer 1 and Timer 2
The time, in milliseconds, that applies to an IP phone session. These timers
are SIP transaction layer timers defined in RFC 3261. Timer 1 is an estimate
of the round-trip time (RTT). Timer 2 represents the amount of time a
non-INVITE server transaction takes to respond to a request.
•
Transaction timer
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. Valid values are 4000 to 64000. Default is 4000.
•
Transport Protocol
The protocol that the RTP port on the IP phone uses to send out RTP packets.
Valid values are 0 (both), 1 (UDP), or 2 (TCP). Default is 1 (UDP).
•
Registration Retry Timer
Specifies the time, in seconds, that the phone waits between registration
attempts when a registration is rejected by the registrar.
