PSTN Settings

When you use your Echo device as a speaker phone to dial into meetings, you must configure the PSTN settings. Alexa for Business uses PSTN settings,and the meeting ID and PIN from the scheduled meeting, to create a dial sequence.

Alexa for Business uses this dial sequence to join the audio conference in the background and send the meeting ID and PIN as dual-tone multi-frequency signaling (DTMF) tones. The specified delays provide pauses before Alexa for Business enters the information. For example, there is a wait, the welcome announcement completes, and the user can enter the meeting ID.
