Distinctive Ringtones
Selects the distinctive ring tone for the matching rule.
When the
incoming caller ID or Alert Info matches the rule, the phone will ring with
the selected ring.
Ring Timeout
Defines the timeout (in seconds) for the rings on no answer. The default
setting is 60 seconds.
Send Anonymous
If set to "Yes", the "From" header in outgoing INVITE messages will be
set to anonymous, essentially blocking the Caller ID to be displayed.
Anonymous Call Rejection
If set to "Yes", anonymous calls will be rejected. The default setting is
"No".
Allow Auto Answer by Call-Info
If set to "Yes", the phone will automatically turn on the speaker phone to
answer incoming calls after a short reminding beep, based on the SIP
info header sent from the server/proxy. The default setting is "No".
Refer-To Use Target Contact
If set to "Yes", the "Refer-
To" header uses the transferred target's
Contact header information for attended transfer. The default setting is
"No".
Transfer on Conference
Hangup
Defines whether or not the call is transferred to the other party if the
initiator of the conference hangs up. The default setting is "No".
Check SIP User ID for
incoming INVITE
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".
Preferred Vocoder
7 different vocoder types are supported on the ph
one, including G.711
U-law (PCMU), G.711 A-law (PCMA), G.723.1, G.729A/B, G.722 (wide
band), iLBC and G72-32. Users can configure vocoders in a preference
list that is included with the same preference order in SDP message.
SRTP Mode
Enables the SRTP mode based on your selection. The default setting is
"Disabled".
Symmetric RTP
Defines whether symmetric RTP is supported or not. The default setting
is "No".
Silence Suppression
Controls the silence suppression/VAD feature of the audio codec G.723
and G.729. If set to "Yes", when silence is detected, a small quantity of
VAD packets (instead of audio packets) will be sent during the period of
no talking. If set to "No", this feature is disabled. The default setting is
"No".
Voice Frames Per TX
Configures the number of voice frames transmitted per packet. When
configuring this, it should be noted that the "ptime" value for the SDP will
change with different configurations here. This value is related to the
codec used and the actual frames transmitted during the in payload call.
