Port Enter the SIP server’s listening port number, if the VoIP service provider gave you
one. Otherwise, keep the default value.
Registration Server IP /
Domain Name
Enter the IP address or domain name of the SIP registrar server, if the VoIP
service provider gave you one. Otherwise, enter the same address you entered in
the SIP IP / Domain Name field. You can use up to 64 printable ASCII
characters.
Port Enter the SIP registrar server’s listening port number, if the VoIP service provider
gave you one. Otherwise, enter the same port number you entered in the SIP IP
/ Domain Name Port field.
Proxy Server IP / Domain
Name
Enter the IP address or domain name of the SIP server or outbound proxy SIP
server (if supplied by your VoIP service provider).
The system uses this address to communicate with the SIP server.
Port Enter the SIP outbound server’s listening port number, if the service provider
gave you one. Otherwise, enter the same port number you entered in the SIP IP
/ Domain Name Port field.
URI Type Use this to configure how Universal Resource Indicators (URIs) are sent.
Select SIP where SIP messages are sent to a domain name or IP
address.
Select TEL where SIP messages are sent to addresses represented
as telephone numbers.
802.1p Priority Set the IEEE 802.1p priority value for SIP and RTP traffic using this SIP profile.
DSCP Set the DiffServ Code Point (DSCP) value for SIP and RTP traffic using this SIP
profile.
Keep Alive Turn SIP session keepalive on or off. When this is on, the SIP UA periodically
sends SIP session refresh requests.
Session Expiration Time Enter the minimum number of seconds after which the system tears down the
session (if no successful session refresh has occurred).
PRACK Sets whether the system sends provisional acknowledgment messages (ON), or
does not send them (OFF).
Resend Set after what percent of the Session Expiration time the IES resends a
registration message. For example, if the session expiration time is 30 minutes
and you set the resend to 50%, the IES resends a registration message after 15
minutes.
NonceCount Keep A SIP server generates a unique string called a nonce for each authentication
exchange with a SIP client. The SIP client includes the nonce with its subsequent
requests. It also includes the number of requests it has sent with the same nonce
value. The SIP server checks the value against its own count to prevent request
replay attacks where an attacker uses the authentication from a legitimate
authenticated request to authenticate a forged request. Receiving the same
nonce count value twice indicates a replay.
Turn this on to have the IES increment the nonce count by one each time it sends
a request. Turn this off to make the nonce count always one.
qop Value Quote Select whether or not the IES adds quotation marks around the qop (quality-of-
protection) value.
Refer-To Bracket For transferring calls, some SIP servers require brackets around the SIP Refer-To
header. Turn these additional brackets on or off.
Refer-To Dot For transferring calls, some SIP servers require the IP address in the SIP Refer-To
header’s Replaces value to be in dotted decimal format. Turn this on to use dotted
decimal format. Turn it off to use %2E instead of dots.
