14.3 Extended Least Cost Routing
Extended Least Cost Routing enables a remote access to the public network (SwyxGate).
Example:
When creating the connection between a SwyxWare user at the London site to a subscriber in the vicinity of the Dortmund site, the SwyxServer at the London site can determine that the dialed subscriber can be reached via the Trunk based on the parameters of the Trunk assigned to Dortmund. This means that the telephone connection from London to Dortmund is e. g. first made via the WAN connection and then via the ISDN Trunk in Dortmund to the external subscriber in ISDN.
A common wish is that the calls from London can signal a calling party number from London. On the "Numbers" tab of the corresponding trunk, you can define which number should be signaled e.g. in ISDN to the called party. The ISDN trunk in Dortmund then must be able to use foreign numbers (i. e. a London number) for outgoing calls. The ISDN function "CLIP no screening" is used for this: it has to be requested separately from your provider.
The Least Cost Routing of the SwyxServer in Dortmund and the corresponding provider is naturally used once again for the connection via the SwyxGate in Dortmund to the external subscriber.
