User's Manual
only by a BYE request.

[0] Disable = (Default) Accepts a CANCEL request received during
the INVITE transaction by sending a 200 OK response and
terminates the call session.

[1] Enable = Rejects a CANCEL request received during the
INVITE transaction by sending a SIP 481 (Call/Transaction Does
Not Exist) response and maintains 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 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:
