valid digits read are treated as noise and discarded. Leading 0 (zeros) digits are allowed,
but not required.
When a valid command is received, the Informer acknowledges the receipt by sending
three short beeps, hanging up, and playing the WAV file or activating the function.
Acknowledgment beeps are not heard if more than one speaker is included in a group
call (phone page).
NOTE: Not all SIP servers will be able to relay acknowledgment beeps if more than one
speaker is included in a group call (phone page).

Standard DV Messages” on page 95 for a complete list.
