Localisation

Fewer standards are more numerous, or diverse, as those governing the facets of international telecommunication. That they may be applied independently at various layers, and change at any junction point in the system, means any system of localisation must be careful to define its domain of influence.

The primary cases we must consider are:

The libvpb api functions for configuring locale specific options can be found here. For functions available at the kernel level, a proc interface also exists at /proc/vt/ for all active hardware.


Electrical standards

The first set of standards to concern us are those of the hardware that will be connected to the Voicetronix card. The OpenPCI and later cards permit selection of the regional hardware standard globally, and provide the ability to override the default on a per port basis.

The selection of a region for a port entirely depends on the device it will be connected to. Each device should be matched for best compatibility from the following list:


Signalling standards

These may be loosely grouped into:
Line signalling
Which includes things like:
  • Hook flash timing
  • Loop drop timing
  • Polarity change
  • Caller ID
  • Dialling
User signalling
Which includes:
  • Ring cadence
  • Call progress tones

User language preferences

There is not presently support for translated text from libvpb, however this will be available at a later time. If you have a pressing need for it sooner than that, then we should chat...
