Asterisk PAGE say time every hour

Digium D6x phones and CyberData SIP Speakers  are used to page.
The phones are also used as intercoms (bidirectional page).

To start, we need accounts for the phones/speakers added to sip.conf:



[phone1] ; Phone
type=friend
host=dynamic
context=my-context
secret=5678
mailbox=319

[speaker1]; Speaker
type=friend 
host=dynamic
context=my-context
secret=1234
mailbox=329
record_out=Adhoc
record_in=Adhoc
qualify=no

Then in extensions.conf, in the [my-context] context, add:

; Paging extensions

exten => 3319,1,GotoIf($[ ${CALLERID(number)} = 319 ]?skipself)

exten => 3319,1,SIPAddHeader(Alert-Info: info=<intercom>) ; Digium D6x require this to enable paging - search documentation for different phone models!

exten => 3319,n,Dial(SIP/phone1) ; this is the phone1 defined in sip.conf

exten => 3319,n(skipself),Noop(Not paging originator)

exten => 3329,1,GotoIf($[ ${CALLERID(number)} = 329 ]?skipself)

exten => 3329,n,Dial(SIP/speaker1,50) ; this is the speaker1 defined in sip.conf

exten => 3329,n(skipself),Noop(Not paging originator)

exten => 398,1,Page(LOCAL/3319@my-context&LOCAL/3329@my-context,di,120) ; Bidirectional PAGE - that's what the "d" does.

exten => 398,n,Hangup()

With this, we can dial 398 and the PAGE should work.

Now, in order to say the time automatically, we need a .call file, let's create /var/lib/asterisk/third-party/say-time.call

Channel: LOCAL/398@my-context

MaxRetries: 10

RetryTime: 5

WaitTime: 20

Context: page-say-time

Extension: 3310

Of course, we need to create the [page-say-time] context in extensions.conf:

[page-say-time]

exten => 3310,1,Answer()

exten => 3310,n,Wait(1)

exten => 3310,n,Playback(at-tone-time-exactly) ; this sound file is already in asterisk sounds

exten => 3310,n,Wait(1)

exten => 3310,n,SayUnixTime(,EST,IMp)

exten => 3310,n,Wait(1)

exten => 3310,n,Playback(beep) ; this sound file is already in asterisk sounds

exten => 3310,n,Wait(2)

exten => 3310,n,Hangup()

and the last step, create a crontab that copies the say-time.call to the astersk outgoing at every fix hour:

0  * *  *  * /bin/cp /var/lib/asterisk/third-party/say-time.call /var/spool/asterisk/outgoing/
