Solved Dialing extension from an IVR

[FS_Mathieu]

Hello guys, we had some experiences with colleagues about dialing an internal extension number while IVR is playing a record.

I tried it with 3CX Support number, the support was in closed hours but while IVR plays, just randomly dial an extension and I finished to another support.

We don't want this to be possible for some customers, is there a way to disable that ?

Best regards,

Mathieu

Hi Mathieu

There is a way to limit this, but it affects ALL IVRs so keep this detail in mind.

The parameter IVR_DIRECT_DIALING_GRAMMAR normally allows digits 0 to 9, with a length of 3 using the default value [0-9]{3}

You can change it to [0-9]{1} which means the digit length is now 1 and cannot call extensions which are more digits.

Ensure you backup first before you make the change, just for your own peace of mind in case it causes any unexpected behavior.

Hello @JohnS_3CX !

That's perfect, exactly what I was looking for ! So we can block extensions calls but that's still working for dialing in IVR Menu.

Thank you
