Direct Dial-in Scenario—SIP Environment
If the IP address of the MCU IP card is known, a direct endpoint to MCU 
connection is possible, but not recommended. This direct connection uses the 
Redirect mode only. 
The SIP endpoint dials the IP address of the IP card or its host name.

Dial-out Scenario—SIP Environment
The dial-out scenario is identical to the dial-in scenario, except for the 
initiating party, that is the MCU. In dial-out conferences, the endpoint clients 
need to be registered, so the registrar can provide location details when the 
MCU invites them to join the conference. 
For example, the MCU dials: 
endpoint1@polycom.com
.
