26.2 WAN connections
Swyx can connect two locations via a WAN (Wide Area Network). In this case, you'll need to differentiate between two basic scenarios:
*Small Office - Connection
A SwyxServer is installed at the London location (A) (e. g., at the headquarters) and there is no SwyxServer at the Liverpool location (B), but rather a network that already has an IP connection to the London location (A) (headquarters).
In this case, it would also be possible to connect the branch office via a SIP gateway trunk.
*SwyxLink (Server Server Link)
Both London (A) and Liverpool (B) have a network with one SwyxServer installed at each location.
A requirement for the WAN connection is an IP connection between London (A) and Liverpool (B). Such an IP connection can be implemented in different ways:
*connection to a Remote Access Server (RAS), as well as a demand-dial connection (dial-in) or a permanent connection (leased line) or
*connection via the Internet.
For information about connecting a branch office to Swyx at the headquarters via a VPN connection using SwyxConnect , please refer to 19 SIP Gateway Links.
