After Call Connection Some Digits are not Received (DTMF Does Not Work)

Problem: When dialing the DID number I can connect to the server but when I enter the PIN code or my phone, some digits are not received in my server, as a result I cannot make calls.

Answer: Please check which VoIP protocol you are using, if you are using H.323 protocol you should make sure that you configured rfc2833 as your default DTMF mode, if it does not work please try to change it to h245signal.

If the problem is not solved please open a support ticket with PIN code for testing.
