Lost DTFM comming inbound

General Help
1

My Free PBX system version 16.0.40.2 Which uses DISA For months suddenly ignoring DTFM’s. I realized that there is the same trouble in the IVR.
Is there a function to reactivate DTMF coming from inbound call.
What is the solution.

Is it lost DTMF? Or one way audio?

Call the IVR internally and test for DTMF to make sure it isn’t your SIP trunk provider on the inbound route with the issue.

when I dial 7777 it say no service at the number you dial.

7777 has nothing to do with this internal test for DTMF.

Add New Virtual Extension > User Extension: 2468 > Display Name: 2468-Test > Advanced > No Answer: IVR, Busy: IVR, Not Reachable: IVR > Submit > Apply Config.

Call 2468 and test your IVR for DTMF.
