Dial Tone
Dial Tone
Sometime, probably close to 20 years ago, but perhaps more recently, you heard a dial tone for the last time and you didn’t even realize it would be.
You're viewing a single thread.
Last time I heard a dial tone was just a second ago when I pushed the speakerphone button on my Cisco ip phone.
It's actually fake, though. IP phones "play" that. Also, when on a call, they insert "comfort noise, that very low hiss you may hear, to augment the odd feeling most get with crystal clear VOIP audio.
It's only a dial tone if it comes from a land line
otherwise it's just sparkling audio lies
Well, it's generated in the same way as modern tones are in a telephone exchange, not a played sample. You can usually configure the tone frequencies (never tried on cisco ip phone, but asterisk allows it for its own generated tones and I had a cisco ATA that let you configure them).
So, unless we're limiting ourselves to the original mechanically generated dial-tones. I'll consider them for all intents and purposes to be one and the same.
E.g. for the UK on cisco/sipura ATAs you would use the configuration found here https://teamhelp.sipgate.co.uk/hc/en-gb/articles/208200875-UK-Regional-Settings-Cisco-Linksys-Sipura-Adaptors and as an example (dial tone)
Dial Tone: 350@-19,440@-22;10(*/0/1+2)
The comfort noise is also generally only added when there's no other noise on the call. This is to prevent you thinking you were disconnected when no-one is talking.
Ceci n'est pas une tonalité
Was coming to type this.
You have an odd fetish
Man....first my mom and now you?
