it to the remote extensions (under Abonnés (Abo) > Propriétés >
Paramètres de ligne).
6. Enable data encryption (see SIPS and SRTP).
7. Configure the STUN server for connecting external VoIP subscribers.
8. Configure the size of the jitter buffer for the remote extensions.
9. Configure the remote extensions. To do this, you need the following
information:
The external IP address or URL of the PBX (as registrar and domain)
The internal number of the VoIP subscribers (as MSN or user name)
The user password of the VoIP subscriber (as registration PIN or
password)
STUN server (the same as in Step 6)
Size of the jitter buffer (the same as in Step 7)
Note: If the Internet connection on the PBX does not have a
permanent IP address, an account with a provider for dynamic DNS is
also required (e.g., dyndns.org). Enter the associated URL in the VoIP
phone as registrar and domain (e.g., pbx.dyndns.org).
10. Check whether the VoIP subscriber was successfully registered on the
PBX (page Surveillance > Statut abonnés internes).
11. If necessary, enable DiffServ in order to increase VoIP call quality
(Quality of Service (QoS)).
