Prestige use the SIP number without a domain name in the SIP
messages that it sends.
Expiration
Duration
This field sets how long an entry remains registered with the SIP register
server. After this time period expires, the SIP register server deletes the
Prestige’s entry from the database of registered SIP numbers. The
register server can use a different time period. The Prestige sends
another registration request after half of this configured time period has
expired.
Register

timer
Use this field to set how long the Prestige waits before sending a repeat
registration request if a registration attempt fails or there is no response
from the registration server.
Session Expires
Use this field to set the longest time that the Prestige will allow a SIP
session to remain idle (without traffic) before dropping it.
Min-SE
When two SIP devices negotiate a SIP session, they must negotiate a
common expiration time for idle SIP sessions. This field sets the shortest
expiration time that the Prestige will accept. The Prestige checks the
session expiration values of incoming SIP INVITE requests against the
minimum session expiration value that you configure here. If the session
expiration of an incoming INVITE request is less than the value you
configure here, the Prestige negotiates with the other SIP device to
increase the session expiration value to match the Prestige’s minimum
session expiration value.
RTP Port Range
Real time Transport Protocol is used to handle voice data transfer. Use
these fields
to configure the Prestige’s listening port range for RTP
traffic. Leave these fields set to the defaults if you were not given a
range of RTP ports to use.
