Asterisk Tutorial 14 - Asterisk Time Conditions

Introducing Asterisk Phone Systems – Introducing Asterisk Time Conditions

It’s time for a Time Check.

For 99.9% of business phone systems in operation today, time conditions are essential for controlling dialplan elements such as Business Hours, which is where the Asterisk IP PBX Application GotoIfTime comes into play, as it allows you to match time conditions against the actual time in order to determine how your Asterisk Dialplan handles the call, for example playing an “Out of Office Hours” or “Public Holiday” notification to the caller.

To find the application within your Asterisk system, simply go to the Asterisk CLI and enter the command core show application GotoIfTime which will open the application and provide some extra information regarding the application. Using Asterisk GotoIftime is fairly straightforward, but you need to aware of some useful pointers on how to actually specify your time conditions.

Obviously, the most common syntax elements within Asterisk Time Conditions include the required time range, days of the week, days of the month and the months themselves. But specifying this information is not enough, as we need a label that indicates what action should be taken – a sort of true or false scenario which matches the actual time with the time conditions you set up within your asterisk dialplan.

An example could be as follows:

exten => incoming number, 1, GotoIfTime (8:00-17:00,mon-fri,*,*?[labeliftrue][:labeliffalse][ [context,]extension,]priority

Important to note here is that day and month names are not case sensitive and if you want to include everyday of the month and every month, you can use the * symbol to include all instead of listing them individually. The ? (question mark) symbol is an essential component as it determines whether the time conditions have been met or not which of course affects how the call will be handled.

When we make decisions regarding new systems, we want to make sure that we have both reins firmly in our hands. Therefore, it is essential to implement systems which adhere to OpenStandards, allowing us to seamlessly connect and integrate these into our existing systems. In addition, we require reliable suppliers, who are ready to customise their solutions to our requirements, which is why we chose pascom who offer exactly this service and more.

Markus Gerlitzki, Managing Director
My team and I pride ourselves on the level of excellent care we provide our guests. However, it can be distracting when the phone is always ringing and we constantly answer the same questions. Thanks to the pascom phone system, we have been able to set up an automated attendant self-service hotline which allows guests to quickly get answers and if required callers can be quickly and efficiently routed to an employee. The system greatly improves customer service with around-the-clock answers around opening times and courses and therefore reduces the strain on employees, ensuring we are free to cater to the needs of our on-site guests.
