Configures the pickup feature code for call park. If "Auto-filling Pickup Feature
Code" is set to "Yes", this pickup feature code will be automatically filled in on the
phone's dial pad when picking up the parked call. This option is used when "Special
Mode" is set to "Broadsoft" and "Enable SCA" is set to "Yes".
Defines line-seize expiration timer. For Shared Call Appearance, the phone must
send a SUBSCRIBE request for the line-seize event package whenever a user
attempts to take the shared line off hook. The default value is 15 seconds. The valid
range is from 15 to 60.
Specifies the mechanism to transmit DTMF (Dual Tone Multi-Frequency) signals.
There are 3 supported modes: in audio, RFC2833, or SIP INFO.
• 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 uses SIP INFO to carry DTMF. The defect of this mode is that it's
easily to cause desynchronized of DTMF and media packet if the SIP and RTP
messages are required to transmitted respectively.
The default setting is "RFC2833".
Configures the RTP payload type that indicates the transmitted packet contains DTMF
digits. The valid range is from 96 to 127. The default value is 101.
Lists the available and enabled Audio codecs for this account. Users can enable the
specific audio codecs by moving them to the selected box and set them with a priority
order from top to bottom. This configuration will be included with the same preference
order in the SIP SDP message.
Lists the available and enabled Video codecs for this account. Users can enable the
specific video codecs by moving them to the selected box and set them with a priority
order from top to bottom. This configuration will be included with the same preference
order in the SIP SDP message.
Configures the phone to use which codec sequence to negotiate as the callee. When
set to "Caller", the phone negotiates by SDP codec sequence from received SIP Invite;
When set to "Callee", the phone negotiates by audio codec sequence on the phone.
The default setting is "Callee".
Configures the phone to use the first matching codec in the 200OK message. The
default value is 0.
Sets the ILBC (Internet Low Bitrate Codec) frame size if ILBC is used. Users can select
it from 20ms or 30ms. The default setting is 30ms.
Configures G726-32 payload type for ITU packing mode. Payload 2 is static and
payload dynamic is dynamic. The default setting is "2".
