Ending a Call

To hang up from a call:

1Press Hang Up on the remote control.

2If prompted, confirm that you want to hang up.

In video calls, if you don’t confirm that you want to hang up, the system disconnects the call automatically after 60 seconds.

In audio-only calls, if the person on an analog telephone hangs up first, you need to disconnect the Polycom HDX system from the call, just as you would hang up a telephone receiver in a regular phone call.

Types of Video Calls You Can Make

Depending on your system configuration, you might be able to make calls using ISDN, H.323, SIP, or V.35/RS-449/RS-530. You can place an audio-only call from Polycom HDX systems that have Analog Phone or Voice Over ISDN enabled.

The following table lists some possible call combinations.
