relayed over T.38.
Notes:
If VBD coder negotiation fails at call start and if the IsFaxUsed
parameter is set to 1 (or 3), then the channel opens with the
FaxTransportMode parameter set to 1 (relay) to allow future
detection of fax tones and sending of T.38 Re-INVITES. In such a
scenario, the FaxVBDBehavior parameter has no effect.
This feature can be used only if the remote party supports T.38 fax
relay; otherwise, the fax fails.
[NoAudioPayloadType]
Defines the payload type of the outgoing SDP offer.
The valid value range is 96 to 127 (dynamic payload type). The default
is 0 (i.e. NoAudio is not supported). For example, if set to 120, the
following is added to the INVITE SDP:
a=rtpmap:120 NoAudio/8000\r\n
Note: For incoming SDP offers, NoAudio is always supported.
Web: SIP Transport Type
EMS: Transport Type
CLI: app-sip-transport-
type
[SIPTransportType]
Determines the default transport layer for outgoing SIP calls initiated by
the device.
[0] UDP (default)
[1] TCP
[2] TLS (SIPS)
Notes:
It's recommended to use TLS for communication with a SIP Proxy
and not for direct device-to-device communication.
For received calls (i.e., incoming), the device accepts all these
protocols.
The value of this parameter is also used by the SAS application as
the default transport layer for outgoing SIP calls.
Web: SIP UDP Local Port
EMS: Local SIP Port
CLI: sip-udp-local-port
[LocalSIPPort]
Defines the local UDP port for SIP messages.
The valid range is 1 to 65534. The default is 5060.
Web: SIP TCP Local Port
EMS: TCP Local SIP Port
CLI: sip-tcp-local-port
[TCPLocalSIPPort]
Defines the local TCP port for SIP messages.
The valid range is 1 to 65535. The default is 5060.
Web: SIP TLS Local Port
EMS: TLS Local SIP Port
CLI: sip-tls-local-port
[TLSLocalSIPPort]
Defines the local TLS port for SIP messages.
The valid range is 1 to 65535. The default is 5061.
Note: The value of this parameter must be different from the value of
the parameter TCPLocalSIPPort.
Web/EMS: Enable SIPS
CLI: enable-sips
[EnableSIPS]
Enables secured SIP (SIPS URI) connections over multiple hops.
[0] Disable (default)
[1] Enable
When the SIPTransportType parameter is set to 2 (i.e., TLS) and the
parameter EnableSIPS is disabled, TLS is used for the next network
hop only. When the parameter SIPTransportType is set to 2 or 1 (i.e.,
TCP or TLS) and EnableSIPS is enabled, TLS is used through the
entire connection (over multiple hops).
