R E M A R K :
===================================================================================
!!! DIAL-PHONES & KEY-PAD-PHONES may not longer work on MODERN (eg. VOIP-) NETS !!!

There are "PULSE-TO-TONE-CONVERTER" on the market for this: I found the "DIALGIZMO"
(~ 50 US$ ) useful  -  There is a way to sent also the "KEY-COMMANDS" [*] & [#] for
automatic menue-guided systems ...
