You can also configure the phone to use a default codec for sending multicast RTP

stream via web interface.

To configure a default codec for multicast paging via web user interface:

The default codec is G722.

Note

To send RTP stream:

1. Press the multicast paging key when the phone is idle.

The phone sends RTP to a preconfigured multicast address (IP: Port). Any phone in

the local network then listens to the RTP on the preconfigured multicast address (IP:

Port). For both sending and receiving of the multicast RTP, there is no SIP signaling

If G722 codec is used for multicast paging, the LCD screen prompts "HD" to indicate that

the phone is providing high definition voice.

Default codec for multicast paging is configurable via web user interface only.
