How to make unencrypted SIP call from a Zoom meeting?

If you really have to make unencrypted SIP call, you can add ";encryption=0" tag to the dial string.

  1. Start the Zoom meeting
  2. Go to Invite, Invite a Room System
  3. Select SIP, enter SIP address and append without space ";encryption=0" e.g. 12345@sip.domain;encryption=0

Prerequisite: You will need Room Connector subscription to make SIP or H323 calls.
