I have a problem that some IVR (call centers of other companies I call, for examp telecom or assurance) doesn’t recognize my actions when I’m in call. The voice tell me ‘press 1 to go to operator’ and when I press 1 nothings happen. Then I need to use classic analogous phone to make this call.
There are other call centers that recognize my actions.
What can be the problem and eventual solution?
I use asterisk 1.4.1 and Snom 300 phone.
