Matrix SETU ATA211 V1 System Manual 141
The CoS bits to be programmed with respect to traffic type are as follows:
By default it is 6.
QoS (Layer 3)
• SIP QoS: ATA will send all SIP messages using SIP QoS (Quality of Service) setting. There are two types
of SIP QoS viz. Precedence and Diffserve. By default, Diffserve is selected. Valid range for Precedence is
from 0 to 7 and for Diffserve is from 00 to 63. By default, Precedence is 5 and Diffserve is 26.
• RTP QoS: ATA will send all the RTP packets with RTP QoS setting. There are two types of RTP QoS viz.
Precedence and Diffserve. By default, Diffserve is selected. Valid range for Precedence is from 0 to 7 and
for Diffserve is from 00 to 63. By default, Precedence is 5 and Diffserve is 46.
Enable SIP over TCP?
This feature allows ATA to send or receive SIP messages over UDP or TCP connection. It is applicable for both
Proxy and Peer to Peer calls. To achieve this, flag is provided as 'Yes' or 'No' for parameter 'Enable SIP Over
TCP?'. It is significant when the option for 'Default Transport for Outgoing Messages' is set as 'TCP' or 'TCP (with
fallback to UDP)'. Refer chapter 'SIP Accounts' for details about default transport for OG messages.
If the flag is set as 'Yes', then only ATA will try to send or receive SIP messages over TCP. Else, the ATA will send
or receive SIP messages over UDP only. By default, it is 'Yes'.
SIP/RTP Port:
• SIP UDP Port: SIP UDP Port defines the port on which the ATA listens for SIP messages transported over
UDP. The ATA also uses this port as source port in SIP messages while sending SIP messages to the
remote peer. The range of SIP UDP Port is 1024-65535. By default, it is 5060.
• SIP TCP Port: SIP TCP Port defines the port on which the ATA listens for SIP messages transported over
TCP. The ATA also uses this port as source port in SIP messages while sending SIP messages to the
remote peer. The range of SIP TCP Port is 1024-65535. By default, it is 5060.
• RTP Listening Port: RTP Listening port defines the port on which the ATA listens for RTP packets. The
ATA also uses this port as source port in RTP packets while sending RTP to remote peer.
The range of RTP Listening Port is 1024-65526. By default, it is 8000.
