Other_Leg Dtmf

[Sebastian]

I have a problem with the option OTHER_LEG. For example, if the other party connection chooses {*} should be directed to the appropriate part of the script. However, we do not attempt to select DTMF on the other side. The name of the module, which supports this is "switch_disconnect_recorded_call".

 

I send the log files.

VG-logs.zip

Attached trace captures two * key-presses:

    Line 20272: 154356.535  21  13   5 ev    dtmf *   (45876059,42,0) ConfOtherLeg=160
    Line 41970: 154709.671  21  10   4 ev    dtmf *   (45876082,42,0) ConfOtherLeg=169

In both cases that keypress is made while script is in module [Wait till end of recorded call], not in module [switch_disconnect_recorded_call] :

154355.340   7  13   5 state [Wait till end of recorded call] Playing wav ()

154644.820   7  10   4 state [Wait till end of recorded call] Playing wav ()

[Sebastian]

Sorry for the mistake. The module, which performs this is [switch_disconnect_not_recorded_call].

In the module, in the "Path" tab, we have:
on {OTHER_LEG_0} goto [some_module]
on {OTHER_LEG_*} goto [some_module]

However, when the other side will select 0 or *, nothing happens.

In VG.ini file, in section [PBX], I removed the line HangupOnDtmf. Could this be the reason?

[SupportTeam]

Trace supplied does not capture any * presses while system is in module [switch_disconnect_not_recorded_call] :

Line 97746: 155206.859   7  28  10 state [switch_disconnect_not_recorded_call] Number Input

In the supplied trace there are 2 cases where * was pressed. Each time the script was is in module [Wait till end of recorded call] at the time.

[Sebastian]

That's right, unfortunately, does not detect DTMF on the other side. Perhaps I should change some settings in the file VG.ini?

[SupportTeam]

When DTMF keys are pressed by the person on the outgoing leg of the call?

 

Are any keys pressed on the outgoing leg of the call detected? Or is it only that * is not detected when pressed on outgoing leg of tromboned conference call?

[Sebastian]

DTMF keys are pressed during the call. Unfortunately, none of the keys is detected. Only the keys pressed by a caller, are working properly.

[SupportTeam]

DTMF tone detection on outgoing legs of transferred call should work.

DTMF detection events should be passed as "OTHER_LEG_X" type events to the script running on the original leg of the call. (the leg connected to originating caller).

 

We have just setup a test on an E1 ISDN test system with a JCT series card (to replicate what you are using) and the DTMF tones from second (outgoing) leg of call are being forwarded to the original leg of call with no problems, appearing there as "OTHER_LEG_X" type events. So not sure what the issue is on your system

 

Can you perhaps try to create a simple test situation where there is a simple 'dial and conference' transfer module and have recipient of the second leg of the call press keys after connection is made and check in traces afterwards to confirm whether you are seeing these DTMF events or not. Please try with different destination telephone numbers/handsets.

[Sebastian]

I noticed that DTMF works on other side when I record the call.

[SupportTeam]

DTMF event forwarding should work regardless of whether the conferenced call is being recorded or not.
