15.6.2 ProviderProfile.config
The profiles for the trunk groups are specified in this file. When creating a trunk group, you can choose depending on the trunk type from various preconfigured profiles (8.1 Create trunk groups).
These profiles define how Swyx interprets numbers for incoming calls and converts them into Swyx-internal formats, and how Swyx-internal numbers are transferred out for outgoing calls.
Example:
You select the profile "Standard DDI" for an ISDN trunk group. This is a profile for a direct dialing-in line to ISDN with the assignment:
Outgoing callCalling party number Extension
Destination number: Subscriber
Incoming callCalling party number Subscriber
Destination number: Extension
The telephone network usually delivers the numbers in the following format:
<Country code><Local area code><Subscriber number><Extension>
Depending on local circumstances, it could also be e.g.:
<Local area code><Subscriber number><Extension>
If a Swyx user (+44 20 4777 225) calls a public line (e. g. 024 3456 555) over this ISDN trunk, the following interpretation arises:This is an outgoing call. The caller number (225) is interpreted by Swyx as an extension and is signaled to the ISDN line as such. The dialed destination number is recognized as a subscriber number of the public network (a subscriber, 024 3456 5555) and is passed in this form as a destination to the public network.
If a subscriber (024 3456 555) calls from the public network and his number type is not recognized, then the called number (destination number) is interpreted as an extension, and forwarded to the internal subscriber with the extension number 225.
