long shot - Asterisk?

mudcow007

anyone on here ever done any programming in Asterisk?

basically trying to make an alarm to run through our PBX

i have set a call file up which works

Channel: local/777@internal
callerid: 777
MaxRetries: 5
Retrytime: 300
WaitTime: 45
Context: Alarm
Extension: s
Priority: 1

within Extensions

[alarm]
exten => s,1,SIPAddHeader(Call-Info:\; answer-after=0)
exten => s,n,Dial(SIP/901,,A(Hello-World)gS(1))
exten =>s,n,Hangup()

this works, but before pushing the call to 901 (our tannoy system) it rings the ext 777. when that extension answers the message is played over 901

once i have this setup i have to figure out "Crontab"

im stumped

That's galling.

Ouch.Chapeau.

Or even Gauling....

I suppose you'd have to be a star programmer...

Hi mudcow

I do Asterisk stuff but have not done call files for some time, I'll have a look at this later this afternoon. It appears like you are nearly there, usually these things need a minor (but potentially time consuming to find) tweak.

Crontab is easier than it looks. What is your OS distro? We use RHEL derived Centos and depending on our needs most of the time we can get away with putting the script into one of the cron directories e.g. /etc/cron.hourly or /etc/cron.daily. This is preferable to mucking around with /etc/crontab directly but even that is not difficult once you get your head around the formatting.

Best regards

I don't know asterisk; but I do know c and c#....

Anyway, I used to be a PBX engineer back in the days when you programmed in Hex codes.... :shock:

Nice to see PBX's using SIP - Ip to desk innit?!

for crontab - assumed to be run as root crontab:

crontab -e to edit the crontab.

crontab -l to view the crontab

There are loads of webpages telling you the time formats and so on, so, I will let you google for that!

Also worth backing up your crontab:

crontab -l > /opt/<<application>>/<<filename>>.bak

mudcow007

cheers guys

distro is ubuntu "fiesty fawn" - never wanted to upgrade as "it works" plus im running a pretty version of asterisk

thanks for the headsup about crontab.

the dialling out thing is messing with my head now, i think ive had about 7 coffees today grr


the master plan is to set up a break time alarm for our factory staff - yes i have already todl them we can buy a standalone system for it. but my md wants me to run it through the pbx

so i will need cron to run the same thing 5 days a week, im pretty sure its just a case of setting the variables

Can you tell me what is not working with your file - what happens when you initiate the call manually? At which stage does it fail?

Crontab is a breeze - last of your worries!

well, as far as im aware, call files need a channel to initiate the call. im my case i have chosen

Channel: local/777@internal (all our extensions are within "internal")

as the call file runs through it pushes the call to context "alarm" an runs through s,1 - this is cool

s,1 adds the auto answer header to the call, which then goes onto our tannoy phone @ 901 an plays "hello world"

the issue is, the channel that is used to initiate the call has to ring an be answered to progress with the call.

so, copy call file to outgoing > extension 777 rings > answer the call > tannoy plays "hello world"

all i want it to do is the tannoy an not ring 777

if thats possible

gtvlusso

Sounds like you need a dummy extn.....or can you call the tannoy port direct?

cookdn

I think I have this figured.

When Asterisk processes the call file it dials the endpoint defined by the 'Channel' parameter. If the dialled endpoint answers then the call flow jumps into your dialplan logic at a position defined by 'Context' and 'Extension'.

Effectively your use of the call file is to dial extension 777, when that is answered the dialplan logic dials extension 901, and when 777 and 901 are connected plays the HelloWorld audio message.

Really what you want to do is dial extension 901 and when answered play your audio message without involving another endpoint. There is a good example of this on the voip-info.org wiki (http://www.voip-info.org/wiki/view/Aste ... foremergen).

However I think I can see why you have gone about this the way you have. You need to send a modified SIP header to your tannoy system to instruct it to automatically answer the incoming call. It looks like you can do this directly in the call file by using the optional 'Set' parameter (http://www.voip-info.org/wiki/view/Aste ... fcallfiles) to specify the required SIP header (http://forums.digium.com/viewtopic.php?f=1&t=16276).

The following call file and dialplan logic should do what I have just described if the information is correct and I have understood things properly.

Channel: SIP/901@internal
callerid: 777
MaxRetries: 5
Retrytime: 300
WaitTime: 45
Context: Alarm
Extension: s
Priority: 1
Set: __SIPADDHEADER=Call-Info:\;answer-after=0

[alarm]
exten => s,1,Answer()
exten => s,n,Wait(1)
exten => s,n,Playback(Hello-World)
exten => s,n,Wait(1)
exten => s,n,Hangup()

Note that this does need at least Asterisk v1.4 for the call file 'Set' parameter to handle dialplan functions.

For scheduling your tannoy messages you can set the modification datetime of the call file to the time in the future when you want it to be processed in addition to writing it out directly using a script and crontab. This might give you some flexibility over scheduling without having lots of crontab entries.

Hope this helps.

Please see below the full extent of my computer programming knowledge:

I hope this helps.

**edit

im a spanner an couldnt type!

David i owe you a beer or three!!

by jingo it works

i had a typo in my set function

i tried your modified dialplan but it failed, its still calling the extension (901)

i had to change your .call file

from : channel: SIP/901@internal
to channel: local/901@

by the looks of it, its not using the "set" function, i also cant see it anywhere in the cli

So the tannoy system (901) is now called direct (777 is no longer involved), but it doesn't auto answer?

ahh you quoted as i edited my post

it was a typo, it now works!

i had a typo on the set function hence why it was ignoring it

i just need to now figure out how i can set it to run multiple times through out the day, every day!

Always the case, I must have burnt up hours on silly typos. Good you spotted it.

What is the schedule for the announcement? The shell script called by crontab shouldn't be too hard.

basically i need crontab to run the "alarm" at 10, 10:15 and 11:00 each day

i understand if i put in * as a variable within day an month it will just keep doing what ever function.

im guessing i can use 1-5 for weekdays?

its the function i need to work out

its the function i need to work out

That's:

0   10,11 * * 1-5 #things to run at 10h00 and 11h00
15  10    * * 1-5 #things to run at 10h15.

Edited for weekday

thanks davis

i need to copy a file an drop it into a specified folder, im guessing this would be something like

0,5,10 * * * *cp /var/spool/asterisk/alarm.call /var/spool/asterisk/outgoing/alarm.call

as a test im hoping i cant get it to run ever 5 mins

muchass grassyarse!

yarp. Although if you want to do it every five minutes then:

*/5 * * * * cp /var/spool/asterisk/alarm.call /var/spool/asterisk/outgoing/alarm.call

Works on most *nixes.

mudcow007

Bloody marvelous!

thanks all

heres the finished article i think


30 8 * * 1-5 cp /var/spool/asterisk/alarm.call /var/spool/asterisk/outgoing/alarm.call
15,30,45 10 * * 1-5 cp /var/spool/asterisk/alarm.call /var/spool/asterisk/outgoing/alarm.call
0 10,11,12,13,14,15 * * 1-5 cp /var/spool/asterisk/alarm.call /var/spool/asterisk/outgoing/alarm.call
15,30,45 14,15 * * 1-4 cp /var/spool/asterisk/alarm.call /var/spool/asterisk/outgoing/alarm.call
30 16 * * 1-5 cp /var/spool/asterisk/alarm.call /var/spool/asterisk/outgoing/alarm.call
