Advantages of the SIP remote gateway:
• The local telephone connection at any site is available for use by
any of the offices throughout the entire company.
• National and international long-distance calls can be mapped to
local or regional calls, so saving costs.
• Automatic routing of incoming calls to the responsible
employee.
1.4.1.5 Connecting sites without a SIP PBX
Companies with widely disperse offices and without their own SIP
PBX can also take advantage of VoIP site coupling. In this "Peer-to-
Peer" scenario, a Swyx VoIP Router has been implemented at both
locations.
Along with data transfer via VPN, it is also possible to use VoIP
functions between the two locations.
The advantages of peer-to-peer site coupling
• ISDN and analog PBXs at different locations can form a
common internal telephone network.
• An SIP PBX is not necessary.
• Calls within the company network are at no charge.
• Outgoing calls are automatically directed to the optimal line for
cost optimization.
• Incoming calls can be switched directly to the appropriate
employee at a different location.
