Parameter Description
■ The corresponding global parameter is
SBC3xxBehavior.
SBC Hold
'Remote Hold Format'
remote-hold-Format
[IPProfile_
SBCRemoteHoldFormat]
Defines the format of the SDP in the SIP re-INVITE (or
UPDATE) for call hold that the device sends to the held
party.
■ [0] Transparent = (Default) Device forwards SDP as
is.
■ [1] Send Only = Device sends SDP with 'a=sendonly'.
■ [2] Send Only Zero Ip = Device sends SDP with
'a=sendonly' and 'c=0.0.0.0'.
■ [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 'Play Held
Tone' parameter is set to Internal.
■ [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.
'Reliable Held Tone Source'
reliable-heldtone-
source
[IPProfile_
ReliableHoldToneSource]
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 'Play Held
Tone' parameter is set to Internal or External.
