Matrix SETU ATA211 System Manual
•
100rel/PRACK:
This parameter is to be configured if you want to support reliable transmission of (SIP)
provisional responses over UDP.
Select the
100rel/PRACK Enable
check box, if you want the SETU ATA211 to use 100rel SIP extension
for reliable transmission of SIP provisional responses and to use PRACK (Provisional Acknowledgement).
Default: Disabled.
•
SIP Over TCP:
SETU ATA211 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.
By default, SIP over TCP is enabled. If you want to receive SIP messages over TCP keep this option
enabled.
You must also enable ‘TCP' or 'TCP (Fallback to UDP)' on the
“SIP Trunks”
.
•
SIP UDP Port:
This is the port on which the SETU ATA211 listens for SIP messages transported over
UDP. This port is also used as the source port for sending SIP messages to the remote peer. The valid
range for this port is 1024–65534. Default: 05060.
•
SIP TCP Port:
This is the port on which the SETU ATA211 listens for SIP messages transported over TCP.
This port is also used as the source port for sending SIP messages to the remote peer. The valid range for
this port is 1025–65526. Default: 05060.
•
RTP Listening Port:
This is the port on which the SETU ATA211 listens for RTP Packets. This port is also
used as the source port for sending RTP packets to the remote peer. The valid range for this port is
1024–65526. Default: 08000.
•
SIP INVITE Timer:
This is the time in seconds for which SETU ATA211 waits for a response from the
called party after sending INVITE message. This timer starts after sending INVITE message to the called
party and stops on receipt of the provisional response or the final response or when the user disconnects
the call. On expiry of the timer, the SETU ATA211 terminates the call process and gives an error tone to
the user. The range of the SIP INVITE TIMER is 010–180 seconds. Default: 30 seconds.
•
SIP Provisional Timer:
This is the time in seconds for which SETU ATA211 waits for final response after
receiving the provisional response from the called party. This timer starts on the receipt of the provisional
response from the called party and stops on receipt of the final response from the called party or when the
user disconnects the call. On expiry of the timer, the SETU ATA211 terminates the call process and gives
error tone to the user. The range of SIP Provisional Timer is 010–180 seconds. Default: 60 seconds.
•
General Request Timer:
This is the time in seconds for which the SETU ATA211 waits for response of a
transaction request. This timer starts on initiating a transaction and stops on the receipt of a response for
the request. On expiry of the timer, the SETU ATA211 clears the transaction. This timer is used for
Registration request, etc. The range of the General Request Timer is 10–60 seconds. Default: 20 seconds.
