Solved DTMF Issues

[greychain]

• 3CX Version, Standard Pro16.0.6.655
• Server OS, Debian 9
• Is the 3CX Server Hosted and where? Self
• IP Phone Make/Model/Firmware - webclient
• Provisioning Method: Local / VPN / STUN / SBC Local maybe
• Trunk Provider or Gateway Make/Model Provider not supported
• Has the Firewall Checker passed: YES / NO mostly
• Are custom Phone Templates being used: NO

I'm making an external call and can see the system is getting DTMF.
The system will not connect me to the extension that I request ie 002.
If I make an internal call to the same DR and press the desired extension it works.

Any thoughts?

A bit more information about your system please.

Sets involved, types of trunks...when you say you are making an external call, do you mean from an external number to your DR, or are you calling another system DR?
Is this a new issue, was it working before?

Turned out to be a firewall issue. There was a VOIP inspection on the firewall that magically got renabled.

Magic can be so frustrating sometimes
