Considerations
■ DTMF signals may be sent to any extension type on the call.
■ If a character sequence with a length greater than 32 is supplied, only the
first 32 characters in the sequence will be accepted (the remaining
characters will be ignored).
■ The ECS does not provide any signal to the adjunct when transmission has
completed.
■ If using the default timing, each digit sent will require 350 ms. Interdigit
timing is 100 ms.
■ While DTMF signals are being transmitted, all parties on the call will be
disconnected from the talk path.
■ If a party drops from the call while tones are being sent and others remain
on the call, signals will continue to be sent to the remaining parties.
■ Tones originating from the ECS will not be listen-disconnected; for
example, Send DTMF tones (generated through ASAI) would still be heard
by the disconnected listener.
■ Send DTMF may not be invoked on a call already receiving any other type
of DEFINITY ECS-generated tone.
