If you want to delete all paging group, you can press the Del All soft key.
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:
1. Click on Features->General Information.
2. Select the desired codec from the pull-down list of Multicast Codec.
The default codec is G722.
3. Click Confirm to accept the change.
Note
To send RTP stream via a multicast paging key:
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
involved.
The multicast paging key LED illuminates solid green.
If G722 codec is used for multicast paging, the LCD screen will display the icon to
indicate that it is providing high definition voice.
Default codec for multicast paging is configurable via web user interface only.
