ith the increasing popularity of VoIP the vendors simply shifted their stance. For example, Nortel developed their Business Communications Manager product. It’s very comprehensive and the Operations Guide runs to some 999 pages, but tellingly it’s intended for the installer, operator and system administrator.

By way of example, the setting Delayed Ring Transfer – which controls the number of rings before the call is forwarded to a prime telephone – can be set to Off, 1, 2, 3, 4, 6 or 10 rings. This is typical of a de-facto industry standard; it began as a gesture towards flexibility but never progressed and it’s now hard-baked into the software.

of rings, the situation germany telegram would have been acceptable to all but the most demanding customers. However, this was not the case.

A little earlier than the shift towards VoIP, computing technology vendors were beginning to exploit the capabilities of cheap high-power CPUs. Database vendors such as Oracle were competing with the likes of Microsoft by lashing together many CPUs to form parallel processing engines. By using commodity CPUs and the Linux operating system, they could deliver huge amounts of processing power at a much lower cost.

The same shift failed to happen in the telecoms industry owing to the dominance of a few major players and their locked-in customers.

The industry needed a paradigm shift and a telecoms consultant called Jim Dixon came up with one. A few manufacturers had already started to build proprietary cards to install in a computer to handle a few POTS lines. The cards required a 286 processor running under MS-DOS. However, these systems were still very expensive and Dixon was growing increasingly frustrated with the costs to his customers.
