Mediant 3000
Parameter Description
[IpProfile_SBCRemoteEarlyMed
iaRTP]
immediately after it sends 18x response with early media. The
device forwards 18x and RTP as is.
 [1] By Media = After sending 18x response, the remote client
waits before sending RTP (e.g., Microsoft Lync environment).
For the device's handling of this remote UA support, see
Interworking SIP Early Media on page 573.
Remote RFC 3960 Support
[IpProfile_SBCRemoteSupports
RFC3960]
Defines whether the destination UA is capable of receiving 18x
messages with delayed RTP.
 [0] Not Supported = (Default) UA does not support receipt of
18x messages with delayed RTP. For the device's handling of
this remote UA support, see Interworking SIP Early Media on
page 573.
 [1] Supported = UA is capable of receiving 18x messages with
delayed RTP.
Remote Can Play Ringback
[IpProfile_SBCRemoteCanPlay
Ringback]
Defines whether the destination UA can play a local ringback tone.
 [0] No = UA does not support local ringback tone. The device
sends 18x with delayed SDP to the UA.
 [1] Yes = (Default) UA supports local ringback tone. For the
device's handling of this remote UA support, see Interworking
SIP Early Media on page 573.
Reliable Held Tone Source
[IPProfile_ReliableHoldToneSo
urce]
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
[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 the 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.
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 = (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 = Used when remote side cannot identify a
