I made an outbound-call service application using Asterisk AMI interface.
Following is how my application works.
I generate an Originate request to internal channel using TCP/IP socket.
my dialplan accepts the request and run dial command. extension.conf file is
[from-internal]
exten => _X.,1,NoOP()
same => n,MixMonitor(${DialMonitorFile}.wav)
same => n,Dial(PJSIP/${EXTEN}#TRUNK_100-1234-5678,30)
What I want to do is record whole call process (from ringback tone sound until user hangup).
But, when dial started, only 44 byte size file is generated (maybe wav file header?) before user accepts the call. And, file increased after user accepts call.
Can someone help me how can I record ringback tone sound as well ?
Regards,
Brian
You should do Answer before MixMonitor if you want that
Please note, CDRs will be affected

I am using Asterisk 15 server and wanted to configure IVR call simulation. My configuration scenario is
1. A subscriber will register to Asterisk server and start a call.
2. The IVR audio will come from the Asterisk sever to sbscriber.
3. Once the subscriber pressed the botton, the call will connect to a number based on DTMF digit pressed by subscriber. Then call will continue for 30 seconds.
I observered for normal call pjsip.conf file is used for configuration of a subscribers.
Could you please help me on below queries ?
1. Which file we need to configure for the IVR call simulation ?
2. Please suggest a good documentation for IVR simulation.
Files are extensions.conf and pjsip.conf/sip.conf
You have read book for beginner, for example "Asterisk the future of telephony".
After that write dialling core or reuse vicidial.org or other core and write dialplan in extensions.conf for you ivr.
What you tried to do usually called "press-1 outbound dialling campaign"
My goal
Pass an incoming call directly to Stasis and allow the app to decide whether to play a ringing or busy tone to the caller.
The problem
With my ARI app, if I omit the same => n,Ringing line from my dialplan, the Stasis app returns an error if the caller hangs up. I can have a call hang without any early media, until I pass a channel.play() command, via the ARI.
This solution has 2 issues:
The Stasis app receives a second StasisStart when the caller hangs up, returning a Channel not found error.
There is no command for channel.busy
Does anyone have any suggestions?
My only option that I can currently see is to ensure that all users have voicemail and a busy tone is never played. Not everyone wants / likes voicemail and it is not ethical to answer the call and play a busy tone, without the caller knowing that their call is connected.
Update
Using the following dialplan, I can get this to work in the desired way (plays busy to a user if they're not available), but with an error:
extensions.conf
[public]
exten => _.,1,NoOp()
same => n,Stasis(myStasisApp, ${SIP_HEADER(to)})
same => n,Busy(10)
same => n,Hangup()
myApp.js
// The user is available
channel.ring();
// The user is busy
channel.continueInDialplan();
Error
Another StasisStart is sent when the caller hangs up, followed by:
Unhandled rejection Error: {
"message": "Channel not found"
}
We faced the same problem and lost precious time finding out the reason so I'm sharing the solution here and maybe it will help.
extensions.conf
[public]
exten => _.,1,NoOp()
same => n,Stasis(myStasisApp)
same => n,Hangup()
When Asterisk receive a call, it will start the stasis app.
Create a Bridge.
Add the incomming channel A in this bridge.
Create a new outgoing channel B from your ari app with POST /channels/create.
Add the outgoing channel B in that bridge.
Dial from channel B the destination, where both of the channels
are in the same bridge with POST /channels/{channelId}/dial
Now, you will be able to see a new ARI Dial events with Ringing and Answer.
For the Hangup, you will receive Channels end events with Hangup Cause Code not a text like 17 for busy
Asterisk Hangup Cause Mappings
It's simpler to originate a channel (Asterisk version 13) instead of create and dial (Asterisk version 14) but you will not have the early media or a full control on that channel because it's created by Asterisk and not the ARI app so this channel will start sending event back to ARI when the call start and not before.

I call to a voice browser with the Dial application on SIP channel in Asterisk. The VXI returns a number. How can I get that number as a return value of the Dial application? ${DIALSTATUS} doesn't get the return value. It has last result of Dial application like ANSWER,NOANSWER,... .
exten => _.,n,Set(VXMLFILE=/var/spool/asterisk/tmp/${EXTEN}.vxml)
exten => _.,n,SipAddHeader(voicexml: ${VXMLFILE})
exten => _.,n,Dial(sip/[some parameters])
Voicexml processing is not part of asterisk, it done by your UA.
So you have consult our UA for result.
Can suggest it allow save log on remote syslog server, so you can parse result from log.
Asterisk cannot directly parse the vxml or xml files.
Create an Asterisk AGI script and parse the vxml file and assign the value to the variable "VXMLFILE".

I am a real beginner in asterisk, so please tolerate my question :)
I tried to configure asterisk for realtime and it is working fine for local sip calls. Now, I am trying to make the following test with dahdi calls:
I connected an analog phone to an FXS channel of my Digium card and tried to call this phone (exten 124) from a sip softphone (X-lite).
I get the following error:
-- Executing [124#from-sip:1] Dial("SIP/2000-00000004", "SIP/124")
[May 31 10:24:22] WARNING[5457]: chan_sip.c:5667 create_addr: Purely numeric hostname (124), and not a peer--rejecting
my extensions.conf:
[from-sip]
switch =>Realtime
[from-pstn]
exten => 124,1,Dial(DAHDI/3)
It seems that the dial is done using from-sip context not from-pstn context as required.
Anyone to advise or correct my understanding?
Thanks million

In Asterisk realtime and not realtime you can configure where to send calls from particular extension, this should be configured in "context"(for realtime check context column), so I believe in your case it is "from-sip". This means all calls from that extension will hit this context, you can't send one call from same extension to one context and other to another, all calls will hit "from-sip" context.
My goal is to :
run a background task activated by dynamic feature while in active call, that will execute dial to another EXT and send DTMF.
It means, when a user is active call with someone, when the user press 5555, the door will be opened.
In order to open the door today, I have to manually call EXT 6(the door) and send DTMF digits: 00*
All of this has to happen automatically when the user press 5555 without interfering the active call.
I tried before to do all of this with dial, but dial blocks the call or bridges with another extension and then I lose the original call.
I figured out that I need to do this with ASYNC, means I can not use dialplan, I need to use CLI, and then originate some how.
Asterisk will need to create a local session / local channel and establish/connect to the door extension, then send DTMF and hangup
All of this – in background.
this is somthing i managed to do so far:
features_applicationmap_custom.conf
openthedoor=> 5555,caller,macro,OpenIntercomCall
then in ->
extensions_custom.conf
[macro-OpenIntercomCall]
exten => s,1,System(asterisk -rx "channel originate SIP/6 extension#yoyo")
i do not understand how do i call to SIP/6 from asterisk(using a local or random channel), and then send DTMF on answer.
the door ext is SIP/6, and 00* is the dtmf to open it.
What i am trying to do is that when a user 5555 in a call, the door will be opened.
means i want asterisk to call the intercom and send dtmf
There are no any sence do exec asterisk from inside asterisk. You can do Originate command.
Originate(tech_data,type,arg1[,arg2[,arg3[,timeout]]])
For example you can do something like this
exten => s,1,Originate(SIP/6,app,SendDTMF,ww00*)
Should be enought for your need.
