Place multiple calls out and then play a message

Asterisk Asterisk APIs
1

Hi,
So currently I am able to call my DID and have it play a recorded message, and I am able to place calls from my DID and play a recorded message when the person being called answers the phone. I want to be able to call multiple people (hundreds) at once to play a recorded message. I’ve looked into it and found autodial plans and agi scripts. Could anyone with more experience tell me the better method to do this? Also, if I use an agi script, would that make it easier to then integrate the Asterisk server into the server of the application we are working on?

Thank you in advance, I appreciate all the help.

Hi @basimkhan, As I remember we have used asterisk java AMI for the same type of requirements and we are pretty satisfy with AMI. You may look into.

Assuming you have a legal relationship with the recipients or you and the recipients are not covered by legal protections…

The 2 most popular ways are ‘call files’ and AMI.

Call files are easier – just create a text file with the correct bits and copy it to your ‘outgoing’ spool directory.

AMI is a bit more efficient, flexible, and has better error control.

AGI has no role here in originating the calls.

Hey thanks for the reply, can I ask how did you go about integrating it into an application once you had used the AMI to place a lot of calls at once?

@basimkhan I used Java AMI to connect with asterisk. For threading I used apache active mq. Using activeMQ I was able to create same number of concurrent thread as same as my number of PRI channels were available.
You may read @JMSListener and its property like concurrency= “dynamic value here as NUMBER OF CHANNELS IN PRI” .

Hey,

Thanks for the reply, would you be able to help me with a connection issue? I can’t seem to figure out why I can use telnet to connect from the server Asterisk is running on, but I can’t use it to connect to Asterisk from the host machine. Is there something I need to do to enable outside connection? That is stopping my java code from authenticating into Asterisk.

@basimkhan You have to edit the manager.conf file in /etc/asterisk folder.
[general]
enabled =yes
port = 1313
bindaddr = 192.168.1.112
displayconnects=yes

[strongUsername]
secret= StrongPassword
deny=0.0.0.0/0.0.0.0
permit=192.168.1.139
read = system,call,log,verbose,command,agent,user,originate,config,cdr,dtmf,reporting,dialplan
write = system,call,log,verbose,command,agent,user,originate,config,reporting,message

Use above config. it will enable you to connect Asterisk through java AMI API code.

Hello,

I was able to connect using Java AMI to my Asterisk server. I can now place calls using the AMI, can you please let me know how you went about calling multiple numbers at once?

Thank you

@basimkhan To call multiple number concurrently, what approach you are trying with. We will help you out in that direction specifically.

Hi,

I was able to place 2 concurrent calls by opening two different ManagerConnections on Java. I then had to add setAsync(Boolean.True), to make sure it called both at the same time. I am now trying to make a loop out of it so I can more than just 2 people, it would be very hectic to have to create a new connection for 100s of people when this goes live.

Thank you

No need to create connection again and again for each call. You should use singleton class for connection.
