X_UseAnonymousFROM Enables using “sip:anonymous@localhost” in FROM
header of SIP INVITE when attempting to make an
anonymous call.
No
X_SessionRefresh Enables session refresh signaling (with SIP Re-
INVITE) during a connected call. This allows the
device to detect if the connection with the peer is
broken abnormally so it can release the call. Disable
this option if the ITSP doesn’t support Re-INVITE
sent from the client device.
Yes
X_SessionTimer Enable standard session timer behavior based on
RFC4028
No
X_SessionExpires Session Expires before value. If session refresh is
enabled, the device refreshes half-time before the
session expires.

the device only accepts SIP requests coming from
one of the given addresses. If the list is empty, the
device accepts SIP requests from any IP address.
X_InsertRTPStats Enables the device to include a X-RTP-Stat header
in a BYE request or 200 response to BYE request at
the end of an established call. This header contains
a summary of RTP statistics collected during the call.

The device handles NOTIFY of this event package
regardless of whether MWISubscribe is enabled.
No

Request-URI, which are otherwise same as
REGISTER.

FROM header as well as the Request-URI as is.
The device forms the Request-URI of SUBSCRIBE
the same way as the TO header, with an additional
port number.
X_MWISubscribeExpires Periodic interval to renew SUBSCRIBE. 3600
