
Silence Compression = Off

Echo Canceller Non-Linear Processor Mode = Off

Dynamic Jitter Buffer Minimum Delay = 40

Dynamic Jitter Buffer Optimization Factor = 13

If the device initiates a fax session using G.711 (option 2 and
possibly 3), a 'gpmd' attribute is added to the SDP in the following
format:

For A-law: 'a=gpmd:8 vbd=yes;ecan=on'

For -law: 'a=gpmd:0 vbd=yes;ecan=on'

When this parameter is set to 1, 2, or 3, the parameter
FaxTransportMode is ignored.

When the value of this parameter is other than 1, T.38 might still
be used without the control protocol's involvement. To completely
disable T.38, set FaxTransportMode to a value other than 1.

For detailed information on fax transport methods, refer to
''Fax/Modem Transport Modes''
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.
Local UDP port for SIP messages.
The valid range is 1 to 65534. The default value is 5060.
Local TCP port for SIP messages.
The valid range is 1 to 65535. The default value is 5060.
Local TLS port for SIP messages.
The valid range is 1 to 65535. The default value is 5061.
Note: The value of must be different than the value of 'SIP TCP
Local Port' (TCPLocalSIPPort).
Enables secured SIP (SIPS URI) connections over multiple hops.

[0] Disable (default).

[1]
Enable.
When 'SIP Transport Type' is set to TLS (SIPTransportType = 2) and
'Enable SIPS' is disabled, TLS is used for the next network hop only.
When 'SIP Transport Type' is set to TCP or TLS (SIPTransportType
= 2 or 1) and 'Enable SIPS' is enabled, TLS is used through the
entire connection (over multiple hops).
Note: If this parameter is enabled and 'SIP Transport Type' is set to
UDP (SIPTransportType = 0), the connection fails.
