Direct, person to person, calls can be made without connecting
to a Marratech Manager server.
Unlike the Private Window functionality, where
you "only" have access to private audio and chat,
this allows you to access all available media, audio,
video, chat, whiteboard and web.
UDP ports 50500 to 50511 must be opened in the firewalls
between the hosts. The Direct Call functionality does not
support Network Address Translation (NAT) networks.
The Marratech Manager offers much better support
for firewalls and NAT and is recommended for extranet
usage. We always recommend communicating via a server running
Marratech Manager which supports most firewall configurations.

First, open the File menu and select Direct Call.
|
 |
Enter the Host name or IP number of
the remote participant's machine. Your own IP number is
shown in the Local Host field for convenience. The other
party that you are "calling" must do the
same step.
Direct Call also supports encryption.
Choose an encryption algorithm (DES, 56 bits or Blowfish,
128 bits) and how you want to access the encryption
key. Choose between Prompt user (mutually
agree on a key to use in advance) or Retrieve
from server where the key is
retrieved from a file
on a secure web server.
