Mediant 500 MSBR
Parameter Description

The database entry expires two hours after the last use.

The maximum number of destinations (i.e., database entries)
is 50.

The corresponding global parameter is SBC3xxBehavior.
SBC Hold
Remote Hold Format
remote-hold-Format
[IPProfile_SBCRemoteHoldForm
at]
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 '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_ReliableHoldToneSour
ce]
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').
