
[1] = Rejects the CANCEL, by responding with a SIP 481
Call/Transaction Does Not Exist, and maintaining the call
session.
Enables the device to reject SIP requests (such as ACK, BYE, or
re-INVITE) whose user part in the Request-URI is different from the
user part received in the Contact header of the last sent SIP
request.

[0] Disable = (Default) Even if the user is different, the device
accepts the SIP request.

[1] Enable = If the user is different, the device rejects the SIP
request (BYE is responded with 481; re-INVITE is responded
with 404; ACK is ignored).
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 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:
