Inbound dialing extensions not working, V20

[FOEngineering]

Hello, when someone calls into our offices, they cannot dial the extension number of who they are trying to reach. Dialing any number while the welcome is going and message just keeps playing. Eventually, it defaults to the "Operator" "0" phone, and then that person can transfer them. We can call each extension directly, phone to phone. I can also dial extensions from my android app to internal phones (from outside the network) and that works. We have tested this with a hard line and cellphone, calling into the offices. Neither allow us to enter the extensions. It's like it's not listening for entries.

We are on a windows install, Version 20.0 Update 2 (Build 715 Release)

Thank you in advance.

A few things to check here:

1. Is the firewall check passing?

If this is passing, continue down, if not, check 1 again.

2. Which codec is used by the provider connection?
3. You can perform a capture on the PBX which will allow you to see if the DTMF tones are reaching the PBX. The disaplay filter is "rtpevent" (without the quote marks).


This is an example of a capture that shows that option number 1 has been pressed.

4. Is this a standard type Digital Receptionist?
