Matrix SETU ATA211G System Manual 67

• UDP NAT Keep Alive: When SETU ATA211G is connected behind a NAT router and SIP messages are

transported over UDP, NAT Keep Alive messages must be sent to refresh the binding in the NAT router.

Select the UDP NAT Keep Alive check box to enable. Default: Disabled.

Select the the type of Keep Alive Message to be sent. You may select either REGISTER or NOTIFY.

Default: NOTIFY.

As Interval, set the time period after which the system should send Keep Alive messages. This time period

should be less than the NAT binding timer of the router. The valid range for the UDP NAT Keep Alive

Interval is 001–999 seconds. Default: 120 seconds.

• TCP NAT Keep Alive: When SETU ATA211G is connected behind a NAT router, and SIP messages are

transported over TCP, NAT Keep Alive messages must be sent to refresh the binding in the NAT router.

Select the TCP NAT Keep Alive check box, if you want the system to send Keep Alive messages

periodically to refresh the binding in the NAT router. Default: disabled.

As Interval, set the time period after which the system should send Keep Alive messages. This time period

should be less than the NAT binding timer of the router. The valid range for the TCP NAT Keep Alive

Interval is 001–999 seconds. Default: 120 seconds.

SIP

• 100rel/PRACK: This parameter is to be configured if you want to support reliable transmission of (SIP)

provisional responses.

Select the 100rel/PRACK Enable check box, if you want the SETU ATA211G to use 100rel SIP extension

for reliable transmission of SIP provisional responses and to use PRACK (Provisional Acknowledgement).

Default: Disabled.

• SIP Over TCP: SETU ATA211G supports transporting of SIP messages over User Datagram Protocol

(UDP) as well as Transfer Control Protocol (TCP) connection. Despite the advantages that SIP over TCP

offers, it is more common to use UDP to transport SIP messages.
