Summary


The most important thing to do concerning the localization of the telephony systems you implement, is to walk in your customer's (and their customers') shoes. This means that you go through every contact and scenario that they would go through with the system (making a call, retrieving a voicemail, and so on) to ensure that everything sounds and appears normal to them.

A point that is made well in the other chapters of this book is that customers will have certain expectations when they pick up a phone. If that phone is on your system, then it's your job to meet those expectations such as familiar dial tone, local language/accent announcements, and so on.

If you're reading this book, you will be the type of person who wants to exceed expectations, and that's great, but these are not the places to do it, people don't want surprises on stuff like this.

The great news is that with the unparalleled (almost infinite) flexibility of Asterisk, you're sure to be able to impress your customers...
