The chart helps you enable/disable the video codec H.264 offered for call setups and set its
priority.
QoS DSCP Value
– set the video RTP packet priority in the network. The set value is sent in
the TOS (Type of Service) field in the IP packet header.
Maximum Packet Size
– set the size limit for the video RTP packets to be sent.
H.264 Payload Type (1)
– set the payload type for video codec H.264 (packetization mode
1). Set a value between 96 and 127 or 0 to disable this codec type.
H.264 Payload Type (2)
– set the payload type for video codec H.264 (packetization mode
2). Set a value between 96 and 127 or 0 to disable this codec type.
Use sendrecv Attribute for Video
– the setting used to be called Compatibility with
Polycom phones. It helps ensure compatibility with some third party devices (Polycom/
Cisco and others). With this mode enabled, the device sends sendrecv instead of sendonly
in its SDP message in the video codec offer.

User Sounds helps you set the audio messages in variable languages to be played during alarm
calls.
