Choose whether certification chain will be validated when TLS/TCP mode is
used.
Choose whether the incoming messages will be validated or not. The default
setting is "No".
If set to "Yes", SIP User ID will be checked in the Request URI of the incoming
INVITE. If it doesn't match the phone's SIP User ID, the call will be rejected. The
default setting is "No".
When set to "Yes", the SIP address of the Request URL in the incoming SIP
message will be checked. If it doesn't match the SIP server address of the
account, the call will be rejected. The default setting is "No".
If set to "Yes", the phone will challenge the incoming INVITE for authentication
with SIP 401 Unauthorized response. Default setting is "No".
This parameter specifies the mechanism to transmit DTMF digits.
There are 3 supported modes:
•
In audio, which means DTMF is combined in the audio signal (not very
reliable with low-bit-rate codecs).
•
RFC2833, which means to specify DTMF with RTP packet. Users could
know the packet is DTMF in the RTP header as well as the type of DTMF.
•
SIP INFO, which use SIP info to carry DTMF. The defect of this mode is that
it's easily to cause desynchronized of DTMF and media packet for the
reason the SIP and RTP are transmitted respectively. Default setting is
"RFC2833"
Configures the payload type for DTMF using RFC2833. Default value is 101.
7 different vocoder types are supported on the phone, including G.711 U-law
(PCMU), G.711 A-law (PCMA), G.723.1, G.729A/B, G.722 (wide band), iLBC,
and G726-32. Users can configure vocoders in a preference list that is included
with the same preference order in SDP message.
When set to "Yes", the device will use the first matching vocoder in the received
200OK SDP as the codec. The default setting is "No".
If enabled, the phone always responses 1 m line in SDP regardless multiple m
lines are offered.
Enables the SRTP mode based on your selection.
Default setting is "Disabled".
Defines whether symmetric RTP is supported or not.
Default setting is "No".
