
[3] Inactive = Device sends SDP with 'a=inactive'.

[4] Inactive Zero ip = Device sends SDP with 'a=inactive' and
'c=0.0.0.0'.

[5] Not Supported = This option can be used when the remote side
does not support call hold. The device terminates call hold requests
received on the leg interfacing with the initiator of the call hold, and
replies to this initiator with a SIP 200 OK response. However, call
retrieve (resume) requests received from the initiator are forwarded
to the remote side. The device can play a held tone to the held
party if the 'SBC Play Held Tone' parameter is set to Yes.

[6] Hold and Retrieve Not Supported = This option can be used
when the remote side does not support call hold and retrieve
(resume). The device terminates call hold and call retrieve requests
received on the leg interfacing with the initiator of the call
hold/retrieve, and replies to this initiator with a SIP 200 OK
response. Therefore, the device does not forward call hold and/or
retrieve requests to the remote side.
Enables the device to consider the received call-hold request (re-
INVITE/UPDATE) with SDP containing 'a=sendonly', as genuine.

[0] No = (Default) Even if the received SDP contains 'a=sendonly',
the device plays a held tone to the held party. This is useful in
cases where the initiator of the call hold does not support the
generation of held tones.

[1] Yes = If the received SDP contains 'a=sendonly', the device
does not play a held tone to the held party (and assumes that the
initiator of the call hold plays the held tone).
Note: The device plays a held tone only if the 'SBC Play Held Tone'
parameter is set to Yes.
Enables the device to play a hold tone to the call party that is placed
on hold. This is useful if the held party does not support play of a local
hold tone, or for IP entities initiating call hold that do not support the
generation of hold tones.

[0] No (default)

[1] Yes
Note: If you configure the parameter to Yes, the device plays the tone
only if the 'SBC Remote Hold Format' parameter is configured to one
of the following: send-only, send only 0.0.0.0, not supported, or
transparent (when the incoming SDP is 'sendonly').
Assigns a Coder Group which defines the supported fax coders for fax
negotiation for the SIP entity associated with the IP Profile. To
configure Coder Groups, see Configuring Coder Groups on page 409.
Note: The parameter is applicable only if you set the
IpProfile_SBCFaxBehavior parameter to a value other than [0].
Enables the device to handle fax offer-answer negotiations for the SIP
entity associated with the IP Profile.

[0] As Is = (Default) Device forwards fax transparently, without
interference.

[1] Handle always = Handle fax according to fax settings in the IP
Profile for all offer-answer transactions (including the initial
INVITE).
