Version 6.8 325 Mediant 500 E-SBC
Parameter Description
Web: Reliable Held Tone Source
CLI: 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 'SBC Play
Held Tone' parameter is set to Yes.
Web: Play Held Tone
CLI: 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: Remote Hold Format
CLI: remote-hold-Format
[IPProfile_SBCRemoteHoldFormat] 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 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 = 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: Remote Replaces Behavior
CLI: sbc-rmt-replaces-behavior
[IpProfile_SBCRemoteReplacesBehav
ior] Enables the device to handle incoming INVITEs containing
the Replaces header for the SIP entity (which does not
support the header) associated with the IP Profile. The
Replaces header is used to replace an existing SIP dialog
with a new dialog such as in call transfer or call pickup.

[0] Standard = (Default) The SIP entity supports INVITE
messages containing Replaces headers. The device
forwards the INVITE message containing the Replaces
header to the SIP entity. The device may change the
value of the Replaces header to reflect the call identifiers
of the leg.

[1] Handle Locally = The SIP entity does not support
INVITE messages containing Replaces headers. The
device terminates the received INVITE containing the
