This applies to calls made to automated services which require you to press buttons on your phone to navigate menus, for example a company which asks you to 'press 1 for sales' etc.

There are different signalling methods for such services - inband, outband and SIP Info.

Telebanking typically expects 'in band' - in fact most PSTN services will, but digital services hosted on VoIP terminations (such as the DrayTEL server) might use SIP Info methods where the keypress is sent as a digital message rather than a digital waveform.

You can select the signally method on the router's VoIP setup menu.
