How to set a telephone prefix

This page documents the directive that allows the app to dial telephone extensions directly. If the prefix or prefixes are correctly set in the home page, say, 012345, you can simply mark as telephone 6789 in a page to create a link that will dial the full number 012345 6789, or a user of the App can dial the full number by typing only the extension.

The directive is a bit complex to set. Don't let this impress you, you can always contact us and let us configure the prefix for you.

How to set a global telephone prefix

In the toolbox HomePage, in the "Editors: Domain Administration form", fill in the "Telephone prefix" text field.

TABLE
Add or fill in the following code adapted for your needs:
6XXX=0123477 [238]XXX=0123488 XXXX=0123456

The different parts of the directive are as follows:

TABLE
Directive |Description
EXT=PREFIX |the rules, what prefix to apply to what type of extensions
6XXX |any 4 digit number starting with 6, like 6543
[238]XXX |any 4 digit number starting with 2, 3, or 8, like 2000
XXXX |any 4 digit number (XXXXX : any 5 digit number, etc.)
=0123477 |the prefix for that type of extension, eg. above for extensions of the type of 6XXX, use the prefix 0123477, ie for the extension 6543, call 0123477 6543.
-6XXX or -XXXX |if an extension type is preceded by "-" (minus), then the first digit of that extension will be dropped.
To drop 2 initial digits, use "--" (2 minuses) before the extension pattern.

In a text page, when an extension link is found, the above rules will be processed one after another, in the order they appear in the directive, until a rule matches the current extension, then that rule will be used for the call. So, place specific rules like 6XXX before more wide ones like XXXX.

Note: to prevent false positives (times, bleeps...), all callable extensions in a page must be marked with the "telephone" style from the edit toolbar. Extensions written in the "Contacts" address book need to be written in the "tel/ext" fields to be callable.

Wait for line or pause:

In the prefix or in the extension, insert a comma "," for the device make one 2-second pause before dialling the rest of the number. For example, a rule XXXX=0123456, (comma at the end) in the directive, then in any page a text 7890 will create an actual link 0123456,7890 and if the user clicks on it, the device will dial 0123456 then wait 2 seconds, then dial 7890.
Insert a semi-colon ";" to make the device wait for a "line in" (connection) before dialling the rest.

Please test the feature out after configuring it, as hospital extensions dialling in is not always what one would expect it to be. Ask the hospital switchboard about the rules if any doubt.
