Configuring the STUN Server for Operation as an External Private Branch Exchange

4. In dependence on the telephone tariffs, restrict the exchange line authorization for
external private branch exchanges (e.g."National"). At times of the day when phone
calls are usually not made, e.g. in the night or outside of business hours, it is possible
to restrict the exchange line authorization to a minimum (under PROPERTIES >
Internal subscribers > Subscriber properties > Exchange line settings).
5. Configure a call restrictor (e.g. for added value services or mobile radiocommunica-
tions networks – 0900, 0180, 01...) and assign it to the external private branch
exchanges (under PROPERTIES > Internal subscribers > Subscriber properties
> Exchange line settings).
6. Configure the STUN server for connecting external VoIP subscribers.
7. Configure the external private branch exchanges. 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)
If necessary, the user PIN of the VoIP subscriber (as registration PIN or
password)
STUN server (the same as in Step 6)
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 telephone as
registrar and domain (e.g., pbx.dyndns.org).
8. Check whether the VoIP subscriber was successfully registered on the PBX (overview
for Status internal VoIP subscribers).
9. If necessary, enable DiffServ in order to increase VoIP call quality.
