When dialing other parties, the following numbering areas are available for use:
- Internal
numbers are comparable to the extension line numbers for traditional
PBX systems ("extension"). Subscribers can reach each other directly
using these internal numbers without having to go through a public telephone
network.
The internal numbers must be unique for all subscribers within the private
telephone network, this also includes any other PBX systems that may
be connected!
The internal subscribers can be reached by simply dialing the internal
number without a "0" preceding it.
Note: Depending on the settings for automatic outside line access, a special preceding dialing signal may be required.
- Via local telephone numbers you can reach external parties who
are in the same local telephone network as the LANCOM VoIP Router,
i.e. users with the same area code as the public line for the LANCOM
VoIP Router.
In decentralized locations that extend beyond city or state boundaries,
the physical location of the device is decisive, even if a central PBX
is located at a different location. Therefore, for a LANCOM VoIP
Router in London, all telephone subscribers in the local telephone
network for London can be reached using local numbers, even if a SIP
PBX connected via VPN can be reached in Manchester.
Note: Depending on the settings for automatic outside line access, a "0" prefix may be required.
- The national and international numbers behave in the same way as local numbers; here, the physical location of the devices is decisive for the assignment of corresponding access codes. Therefore, a LANCOM VoIP Router in Austria belongs to the national telephone network in Austria, even if there is a VPN connection to the SIP PBX at the headquarters in Germany.
Note: Depending on the settings for automatic outside line access, a "0" prefix
may be required.
