Server Port
Enter the SIP server’s listening port for the SIP in this
field. Leave this field set to the default if your VoIP
service provider did not give you a server port
number for SIP.
Service Domain
Enter the SIP service domain name in this field.
URL Scheme
Select SIP-URL to have the router include the domain
name with the SIP number in the SIP messages that
it sends. Select TEL-URL to have the router use the
SIP number without a domain name in the SIP
messages that it send.
User Parameter
You can set this to phone or none. This determines
whether or not the phone number is appended to the
information forwarded to your SIP server. Your VoIP
service provider will instruct you which setting to use.
Initial Unregister
You can set this to enabled or disabled. Some SIP
servers can become unstable if you are registered
more than once (due to a power outage and
subsequent reboot of the router, for example). This
setting allows your router to “unregister” itself when it
is rebooted, removing the previously sent registration
information.
Register Expires
Use this field to set how long the router will wait
before sending a repeat registration request if a
registration attempt fails or there is no response from
the registration server.
Session Expires
This field will set the longest time that the router 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 router will accept. The router checks the
session expiration values of incoming SIP INVITE
requests against the minimum session expiration
value that you enter here. If the session expiration
of an incoming INVITE request is less than this value,
the router negotiates with the other SIP device to
increase the session expiration value to match the
minimum session expiration value.
Session Expires Refresher
This determines which side of an expired call session
will initiate the session refresh. uac – specifies the
Caller side will initiate the session refresh. uas
specifies the Call receiver (the “Callee”) will initiate
the session refresh.
