Q.: DTMF generated by SIPPS is not recognized by other
      applications.

SIPPS generates DTMF based on the standard set-op for DTMF for PSTN
telephones. SIPPS transmits DTMF as tones and not as events. Hence, any
application awaiting an event instead of a tone will not be able to work
with SIPPS
