User's Manual
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).
Defines the maximum number of concurrent calls per IP Profile (see
''Configuring IP Profiles'' on page 391).
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:
