Parameter Description
Web: SBC Remote Hold Format
[IPProfile_SBCRemoteHoldFor
mat]
Defines the format of the SDP in the re-INVITE for call hold that
the device sends to the held party.

[0] transparent = Device forwards SDP as is.

[1] send-only = Device sends SDP with 'a=sendonly'.

[2] send only 0.0.0.0 = Device sends SDP with 'a=sendonly'
and 'c=0.0.0.0'.

[3] inactive = Device sends SDP with 'a=inactive'.

[4] inactive 0.0.0.0 = Device sends SDP with 'a=inactive' and
'c=0.0.0.0'.

[5] not supported = Used when remote side cannot identify a
call-hold message. The device terminates the received call-
hold message (re-INVITE / UPDATE) and sends a 200 OK
to the initiator of the call hold. The device plays a held tone
to the held party if the 'SBC Play Held Tone' parameter is set
to Yes.
Web: SBC Play Held Tone
[IpProfile_SBCPlayHeldTone]
Enables the device to play a held tone to the held party. This is
useful if the held party does not support playing a local held
tone, or for IP entities initiating call hold that do not support the
generation of held tones.

[0] No (default)

[1] Yes
Note: If this parameter is set to Yes, the device plays the tone
only if the 'SBC Remote Hold Format' parameter is set to
transparent, send-only, send only 0.0.0.0, or not supported.
Web: SBC Reliable Held Tone
Source
[IPProfile_ReliableHoldToneSou
rce]
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.
