via the Internet as a VoIP call.
Connecting subsidiaries or home offices to the headquarters
Many subsidiaries or home offices already have a connection to the network
at headquarters over VPN. These connections are normally limited to conven-
tional data transmission. By using VoIP, internal company calls can be made
for free over the existing VPN connection and— thanks to the VPN
encryption —these calls are secured against eavesdropping.
With a LANCOM VoIP Router located in the branch or home office, the two
worlds of traditional (ISDN and analog) and VoIP telephony can be united in
a single telephone: A SIP telephone or an existing analog or ISDN telephone
can be used for free telephone calls via VPN to the headquarters, or to make
standard calls via the conventional telephone network.
The advantages of a telephone connection to headquarters:
The configuration of telephone functions can be carried out centrally in
the VoIP PBX at headquarters.
Subscribers at their branch or home offices connect with the central PBX.
Calls within the company network are free.
Outgoing calls are automatically directed to the optimal line for cost opti-
mization.
