Hello to all,
I have a Problem and 2 Question, i found a Document by Swisscom (only in German) with the Name "schnittstelleneigenschaften_de.pdf" ther are a lot of information and links to ETSI ... But now my first Problem ther is a "Supervisory tone" called Spezialsummton 2 (special dial tone) with this Tone levels and cadences
Cadence : 0,5 s on / 0,05 s off Frequency : 425 Hz +/- 15 Hz Level : -6.2 bis - 19.7 dbm
Can somewhere say me when this special dial tone 2 is playing by Swisscom ?
My 2nd Question or Problem is in the same Document there are talking about MWI (Message Waiting Indicator) and ther link to a ETSI Document wehre ther describe when and how to send a FSK signal when the telephone ring to notice on the display that the customer has a message on his voicemail. But ther dont say with dial tone the customer need to listen if ther is a message on his voicemail. Do somewehre know with dialtone i need to play if ther is a message on his voicemail that he know he need to listen his voicemail if his phone has no symbol to show the MWI Symbol.
