User's Manual 21. Coders and Profiles
Parameter Description
Web: SBC RFC2833 DTMF
Payload Type Value
[IpProfile_SBC2833DTMFPayloa
dType]
Defines the RFC 2833 DTMF Payload Type for a specific SBC
leg. This enables the interworking of the DTMF payload type for
RFC 2833 between different SBC call legs. For example, if two
entities require different DTMF payload types, the SDP offer
received by the device from one entity is forwarded to the
destination entity with its payload type replaced with the
configured payload type, and vice versa.
The value range is 96 to 127. The default is 0 (i.e., the device
forwards the received payload type as is).
Web: SBC User Registration Time
[IpProfile_SBCUserRegistration
Time]
For a description, see the global parameter
SBCUserRegistrationTime.
Web: SBC Remote Hold Format
[IPProfile_SBCRemoteHoldFor
mat]
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 0.0.0.0 = Device sends SDP with 'a=sendonly'
and 'c=0.0.0.0'.
 [3] inactive = Device sends SDP with 'a=inactive'.
 [4]
inactive 0.0.0.0 = 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: SBC 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: SBC Reliable Held Tone
Source
[IPProfile_ReliableHoldToneSou
rce]
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.
