[QoSStatistics]
■ Handling In-dialog Requests: If the
VerifyRecievedRequestUri parameter is configured to [1] or [3],
for all incoming in-dialog requests (including ACK and CANCEL),
the device checks if the Request-URI user part matches the
remote Contact user part (i.e., the Contact user configured for
the Account). If there is no match, the device rejects the request
and sends a SIP 481 response for requests such as BYE and
CANCEL, or a SIP 404 for other requests, and for ACK it does
not send any response.
Defines a Proxy Set for the registrar. The parameter functions
together with the VerifyRecievedRequestUri parameter. For more
information, see the description of the VerifyRecievedRequestUri
parameter.
The default value is -1 (not defined).
Note: This setting assumes that the SIP Interface has only one regis-
trar.
Defines the maximum number of simultaneous active calls
supported by the device. If the maximum number of calls is reached,
new calls are not established.
The valid range is 1 to the maximum number of supported channels.
The default value is the maximum available channels (i.e., no
restriction on the maximum number of calls).
Enables the device to include call quality of service (QoS) statistics
in SIP BYE and SIP 200 OK response to BYE, using the proprietary
SIP header X-RTP-Stat.
■ [0] Disable (default)
■ [1] Enable
The X-RTP-Stat header provides the following statistics:
■ Number of received and sent voice packets
■ Number of received and sent voice octets
■ Received packet loss, jitter (in ms), and latency (in ms)
The X-RTP-Stat header contains the following fields:
■ PS=<voice packets sent>
■ OS=<voice octets sent>
■ PR=<voice packets received>
■ OR=<voice octets received>
■ PL=<receive packet loss>
■ JI=<jitter in ms>
■ LA=<latency in ms>
Below is an example of the X-RTP-Stat header in a SIP BYE
message:
BYE sip:302@10.33.4.125 SIP/2.0
