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.
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.
Enables the device to play Music-on-Hold (MoH) to call
parties that are placed on hold. This is useful if the held
party does not support the 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) The device does not play any tone to
held call parties.
■ [1] Internal = Plays the local default hold tone or a tone
defined in the PRT file (if installed).
■ [2] External = Plays MoH audio streams that originate
from an external media source. For more information,
see Configuring SBC MoH from External Media Source
on page 601
Note: If you configure the parameter to Internal, 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').
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
Coder Groups.
Note: The parameter is applicable only if you set the
IpProfile_SBCFaxBehavior parameter to a value other than
[0].
