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".
Specifies the G726-32 payload type, and the valid range is 96 to 127. The
default setting is "126".
Defines the desired value (96-127) for the payload type of the Opus codec.
The default value is 123.
Enables/disables RFC5168 mechanism for video calls. RFC5168 allows
SIP party to request the sender to refresh its video frame in H.264, or
refresh the full picture in VP8.The default setting is "No".
When enabled, the video sender will temporarily allocate part of the
bandwidth to one data channel to send FEC data to system, thus to
improve the video quality the receiver gets. Enabling this function will take
up part of bandwidth and reduce call rate. The default setting is "Yes".
When set to 0, FEC is not sent by separate port. If set 1, FEC is sent by
separate port. Default setting is 0.
Configures FEC payload type. The range is 96-127. The default setting is
120.
Configures the packetization mode for the video packets during the video
calls. Three lodes are supported:
•
Single NAL Unit Mode: the packetization mode will be negotiated
as single NAL unit mode when dial video calls, if the other party
does not support the negotiation, then single NAL unit mode will
be used for video encoding by default.
•
Non-Interleaved Mode: the packetization mode will be negotiated
as Non-interleaved mode when dial video calls, If the other party
does not support negotiation, then the Non-interleaved mode will
be used for video encoding by default;
•
Prefer Non-Interleaved Mode: the packetization mode will be
negotiated as prefer Non-interleaved mode when dial video calls,
if the other party does not support the negotiation, then prefer Non-
interleaved mode will be used for video encoding by default.
The default setting is "Prefer Non-Interleaved Mode".
Sets the H.264 image size. It can be selected from the dropdown list.
