Parameter Description

The corresponding global parameter is SBC3xxBehavior.
SBC Hold
Remote Hold Format
remote-hold-Format
[IPProfile_SBCRemoteHoldF
ormat]
Defines the format of the SDP in the SIP re-INVITE (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 '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.
Reliable Held Tone Source
reliable-heldtone-source
[IPProfile_ReliableHoldTone
Source]
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.
Play Held Tone
play-held-tone
[IpProfile_SBCPlayHeldTone
]
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').
