Parameter Description

[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_ReliableHoldToneS
ource]
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').
SBC Fax
Fax Coders Group
sbc-fax-coders-group-name
[IpProfile_SBCFaxCodersGro
upName]
Assigns a Coder Group which defines the supported fax coders for
fax negotiation for the SIP entity associated with the IP Profile. To
configure Coder Groups, see Configuring Coder Groups on page
415.
Note: The parameter is applicable only if you set the
IpProfile_SBCFaxBehavior parameter to a value other than [0].
Fax Mode
sbc-fax-behavior
[IpProfile_SBCFaxBehavior]
Enables the device to handle fax offer-answer negotiations for the
SIP entity associated with the IP Profile.
 [0] As Is = (Default) Device forwards fax transparently, without
interference.
 [1] Handle always = Handle fax according to fax settings in the IP
Profile for all offer-answer transactions (including the initial
INVITE).
 [2] Handle on re-INVITE = Handle fax according to fax settings in
the IP Profile for all re-INVITE offer-answer transactions (except
for initial INVITE).
Note: The fax settings in the IP Profile include
IpProfile_SBCFaxCodersGroupName, IpProfile_SBCFaxOfferMode,
and IpProfile_SBCFaxAnswerMode.
Fax Offer Mode Defines the coders included in the outgoing SDP offer (sent to the
