Asterisk time based routing

Here is an example of routing calls over time in Asterisk.
Assume that the /etc/asterisk/extensions.conf file has a configured context for the trunk with the following parameters:

[Trunk_2]
exten => s,1,DIAL(SIP/6004&SIP/6003,19)
exten => s,2,Hangup()

And to resolve the time calls to different phones, we will point out for the context of this trunk only nested contexts:

[Trunk_2]
include => daytime,8:00-18:00,mon-sat,*,*
include => nighttime,18:00-8:00,mon-sun,*,*
include => sunday,8:00-22:00,sun,*,*

In fact, daytime, nighttime, sunday are only the names of contexts for which the time is written in the context of [Trunk_2], they can be called anything.

And then in these separate contexts we will already add the necessary extensions.
That is, in the afternoon:

[daytime]
exten => s,1,DIAL(SIP/6004&SIP/6003,19)
exten => s,2,Hangup()

At night:

[nighttime]
exten => s,1,DIAL(SIP/6002,19)
exten => s,2,Hangup()

And on Sunday:

[sunday]
exten => s,1,DIAL(SIP/6002,19)
exten => s,2,Hangup()

You can also, for example, create a holiday context with holidays:

include => holiday,*,*,1,jan
include => holiday,*,*,8,mar

etc.

For those who want to paint more in detail by day, I’ll give you a list of days in English:
mon – Monday
tue – Tuesday
wed – Wednesday
thu – Thursday
fri – Friday
sat – Saturday
sun – Sunday

Similarly, up to three letters and names of months are shortened.
