webservice

[Soli]

Hi

I’m working with Call Flow Designer and using Web Service components.

My flow is as follows:

1. The first Web Service is called and returns a valid response.
2. After that, I play an audio message that is about 20 seconds long.
3. Only after the audio finishes, the call should continue to a second Web Service, which should then return another response.

However, in practice, the second Web Service is triggered almost immediately (after about one second), instead of waiting for the 20 second audio message to finish.


My main requirement is that the second Web Service will be executed only after the audio playback is fully completed.


Is this expected behavior?
How can I make sure that the second Web Service runs strictly after the audio message ends?

Thanks in advance for your help.

Is this expected behavior?

no

Was the option 'Accept DTMF Input' disabled in the CFD module?
Does the announcement actually exist, and can the CFD app access and play it? Has this been tested before?

I would set the 3CX Activity log logging level to verbose and check the 3CXCallFlow.log to see at what time which component is called with which parameters. I might also add custom logger modules and check that in the log.

In 3cx logs i can see that the first one is on i received response then it move to play the message (which is working properly) and after one second the second Webservice is on so it's not waiting for the message to fully played it's just trigger it and move to the next thing which is the webservice

Just for you I tested it - just to be sure, you never know ...

This little functional snippet works exactly as expected: REST request, playback of the entire audio and only after that does the next request come.

Hi,

What's the PBX version/install and what version of CFD are you running?

 

[fxbastler]

After that, I play an audio message that is about 20 seconds long.

What exactly is being played?
A single file that is permanently stored in the CFD app, a dynamic selection, a mixed variety? Please describe it.

 

[Soli]

it play single file

PBX Version 20.0 Update 7 (Build 1080 Release
CF 20.2.84.0

 

[fxbastler]

As written and rebuilt and tested for you once again: this should work. That's how I know it as well.

What happens if you further reduce the CFD code or simplify the API request for testing?

For the test example, I sent a simple GET request to https://ifconfig.me/ip, so it's not a fully-fledged REST request with login, headers and data.

 

[Soli]

first thank you very much

did you check in call flow logs and saw that the second request is really after 20 seconds in your example?

 

[fxbastler]

yes

If I reduce the log level and logger output is on error, it looks like this:

2025/12/16 12:26:21.216|0005|Info| New Severity is set Warning

My audio file isn’t 20 seconds long, it’s shorter, but it plays fully. The length shouldn't matter, not in this case

 

[Soli]

thank you
i guess it's a bug or something

 

[KyriacosS_3CX]

not in this case

Ts, ts, ts...

 

[fxbastler]

Ts, ts, ts...

What you think again - I obviously meant that purely from a technical functionality perspective, I swear

 

[Soli]

I'm still facing the same issue any other thoughts ?

The first webservice is working fine than I hear the 20 seconds Message like the flow should be but in the same time the second Webservice stats and not after the message end which cause the Response code to be wrong

I am observing similar issues with my CFD projects that are not even related to Web Services. These are projects that were built years ago and had been working fine until recently. It seems as if the call flow process sometimes executes components far ahead of the caller's actual position in the script.

As a workaround, I propose changing the Prompt Playback component. Instead, use the Menu component. Set the Timeout to 1 second and Max Retries to 1, then place your audio file in the Initial Prompt. This seems to work for me, as the Menu component forces the script to wait for the caller's choice, which pauses further execution until that moment.

Hello @Soli,

In your Prompt Playback component, ensure that the property AcceptDtmfInput is set to false. This setting controls if the message is queued to be played later, or it is played immediately. If the AcceptDtmfInput property is set to true, the prompt is just added to a queue, to be played in the next Menu or User Input. This allows the user to cut through with a DTMF.

That will solve the issue.

@Soli

You must have changed something critical in the call flow. The log output doesn't match the image you showed above. The Line

2025/12/17 11:30:32.755|0010|Trac| [_3CX.Script] _698_37.Main.30.[C:7.3]-conditionalComponentBranch1 - CallFlow.CFD.SequenceContainerComponent 'conditionalComponentBranch1' - No inner components, moving to the next component...

indicates that there are no CFD components in that branch. This line should instead have the following content:

conditionalComponentBranch1 - CallFlow.CFD.SequenceContainerComponent 'conditionalComponentBranch1' - Start executing component 'promptPlaybackComponent2'

Please take a actual screenshot of the CFD project.

Alternatively, clean up your CFD project by removing any sensitive information and post the entire packed CFD project here.

One more question: Is this a Windows or a Debian 3CX?

 

[fxbastler]

@edossantos_sipcaller

Was the option 'Accept DTMF Input' disabled in the CFD module?

What can you do, people just don’t listen …

 

[edossantos_sipcaller]

@edossantos_sipcaller

What can you do, people just don’t listen …

Yes, I saw your question regarding this, but it seems this was not changed, because what the user describes is exactly what this property will do. I was trying to be more precise in terms of where the setting should be changed. By doing this change the issue should be solved.

Maybe other problem, maybe other solution, but pls. look at the latter answers above.

You say that the projects have been running for many years: were the projects recreated with the current v20 CFD after the 3CX upgrade to v20?
