Gateway Calls
The RMX can be used as a gateway that provides connectivity across 
different physical networks and translates multiple protocols for point-
to-point rich media communications.
The RMX supports the widest range of video and audio algorithms. It 
allows sites with different frame rates, connection speeds, audio 
algorithms, video resolutions and network protocols to transparently 
connect with one another. It also enables multipoint conference creation 
from an endpoint.
A special conference acting as a Gateway Session is created on the RMX. It 
includes one dial-in connection of the endpoint initiating the Gateway 
Session and one or several dial-out connections to endpoints. It provides 
connectivity between the various protocols: H.323, SIP, ISDN and PSTN.   
To enable the gateway functionality a special Gateway Profile is defined 
on the RMX.
Call Flows
Two calling methods are available:
Direct (IP participants)
Via Gateway IVR (IP and ISDN/PSTN participants)
Direct Dialing
This calling method is available to IP participants only and is the 
recommended method.
The calling endpoint enters the dialing string that includes the access 
numbers to the RMX Gateway Profile and the number of the destination 
endpoint. Up to 10 destination numbers can be entered in one string.
The call connects to the RMX Gateway Profile and a Gateway Session is 
created. The dial-in participant is automatically connected to it.
