User's Manual
Determines whether the device sends the initial INVITE message with or
without an SDP. Sending the first INVITE without SDP is typically done by
clients for obtaining the far-end's full list of capabilities before sending
their own offer. (An alternative method for obtaining the list of supported
capabilities is by using SIP OPTIONS, which is not supported by every
SIP agent.)

[0] Disable = (Default) The device sends the initial INVITE message
with an SDP.

[1] Enable = The device sends the initial INVITE message without an
SDP.
Enables the device to send "a=crypto" lines without the lifetime parameter
in the SDP. For example, if the SDP contains "a=crypto:12
AES_CM_128_HMAC_SHA1_80
inline:hhQe10yZRcRcpIFPkH5xYY9R1de37ogh9G1MpvNp|2^31", it
removes the lifetime parameter "2^31".

[0] Disable (default)

[1] Enable

INVITE requests to 'anonymous' for restricted calls.

[0] Disable (default)

Determines whether the device uses the value of the incoming SIP
Reason header for Release Reason mapping.

[0] = Disregard Reason header in incoming SIP messages.

[1] = (Default) Use the Reason header value for Release Reason
mapping.
Determines the device's behavior upon receipt of SIP Re-INVITE
messages that include the SDP's 'silencesupp:off' attribute.

[0] = (Default) Disregard the 'silecesupp' attribute.

[1] = Handle incoming Re-INVITE messages that include the
'silencesupp:off' attribute in the SDP as a request to switch to the
Voice-Band-Data (VBD) mode. In addition, the device includes the
attribute 'a=silencesupp:off' in its SDP offer.
Note: The parameter is applicable only if the G.711 coder is used.
