The out-band DTMF transmit s dialing tones over protocols, such as RFC2833 and
SIP INFO, which can ensure the validity of the transmission.

The media advance setting is set for the RTP media stream of the gateway. Select
“Call Setting” > “Media” and the following setting parameters are displayed:
A. RTP Port (Range)
This parameter is used to specify the UDP of the RTP and used with the router
port for mapping. Note: The terminal will use multiple pairs of RTPs (depending
on the number of lines that the terminal supports). The value of this parameter
ranges from 5500 to 5520.
B. Packet Length (ms)
This parameter indicates the duration of sending a network packet. If this
parameter is null, it indicates that the default value is 20ms. It is used to specify
the size of the media packet. The unit is ms (the actual number of bytes depends
on the compression algorithm).
