8.7 Forwarding and number substitution
Outgoing calls can be made depending on
*the phone number of the calling SwyxWare user,
*of the dialed number,
*of group membership,
*the location of the user and/or
*the time conditions,
be forwarded via various routes.
A forwarding entry is always assigned to a specific trunk group.
You can also use placeholders when defining rules, see Placeholder.
Example:
You have an ISDN trunk to the public telephone network in Hamburg and a SwyxLink connection to a branch office in Berlin. All calls to Berlin (+4930*) should be routed via SwyxLink.
You set up a forwarding for the trunk group SwyxLink is a member of (destination number/URI: +4930*), setting a high priority e.g. 900. Set up a route for the ISDN trunk group (e. g. for England- destination number/URI: +44*), but with a low priority (e. g. 100). If the line is busy, i.e. all configured channels are in use, interrupted or deactivated, the calls will be established via the low priority connection (here: ISDN).
If you later set up an economical SIP connection, you can specify a route for this for all of the United Kingdom (+44*) with a higher priority (e. g. 800). The connection attempts are made according to priority order, i.e. in this case the SwyxLink connection is selected first, then the SIP connection and then the connection via ISDN.
* 
If a user has used the selection prefix to specify a trunk group through which the call should be routed, no forwarding rules are applied to that call.
