This parameter defines the local SIP port the HandyTone ATA will listen and
transmit. The default value for FXS port is 5060. The default value for FXO
port is 5062.
This parameter defines the local RTP-RTCP port pair the HandyTone ATA will
listen and transmit. It is the base RTP port for channel 0. When configured,
channel 0 will use this port _value for RTP and the port_value+1 for its RTCP;
channel 1 will use port_value+2 for RTP and port_value+3 for its RTCP. The
default value for FXS port is 5004. The default value for FXO port is 5008.
Default is No. If set to Yes, Call Forwarding & Do-Not-Disturb are supported
locally
This parameter controls how DTMF events are transmitted. There are 3 ways:
in audio which means DTMF is combined in audio signal (not very reliable
with low-bit-rate codec), via RTP (RFC2833), or via SIP INFO.
This parameter sets the payload type for DTMF using RFC2833
This parameter specifies the number of FXS phone rings for incoming PSTN
calls to FXO port. Default is 4.
The HandyTone ATA supports up to 7 different Vocoder types including G.711
A-/U-law，G.723.1, G.726, G.728, G.729A/B, iLBC. Depending on the
product model, some of these Vocoders may not be provided in standard
release.
Users can configure Vocoders in a preference list that will be included with the
same preference order in SDP message. The first Vocoder in this list can be
entered by choosing the appropriate option in "Choice 1". Similarly, the last
Vocoder in this list can be entered by choosing the appropriate option in
"Choice 7".
