- Hi All, A telephone question...
-
- We all know that public telephones do their charging in multiples of 30c
- (Telecom Owned ones) and that the way the phone works out when to hit you for
- more $ is a 'billing pulse' is sent every so often that the phone detects.
- (If you get the right line, you can actually hear the pulse...)
-
- My Problem. I own one of those fan-dangle whiz-bang Tytel (Australian made,
- from Artarmon - no longer exist) Telephones that makes you breakfast,
- redials your call, and detects billing pulses to give you a fairly accurate
- estimate of what your bill will be.
-
- It works by counting local calls at one local fee (you tell it the fee
- = $0.25 for home phone) and multiplying billing pulses by the local fee
- to establish how much STD calls cost...
-
- At least that is what the manual says...
-
- The plot thickens... The phone also asks for the area code in which is is
- operating so that when it catches you dialing a STD code, it can use
- that and an internal data-base to work out the distance and thus the call
- charge.
-
- Yes, you are right, I have just contradicted myself.... Do we calculate time,
- of billing pulses...?
-
- Question (1): Does anyone know which way my phone is *really* working
- out my bill?
-
- OK, now it gets even better... Given the cost of a local call, and the
- local area code and the area code to which we are calling. The phone
- also knows the time of day (it has a clock). The billing calculations
- seem to be pretty accurate for peak times, but not so for Night and
- Economy Rates... Suggests it is not using billing pulses but is
- trying to calculate itself doesn't it...
-
- Anybody got any clues...?
- Do home fones actually get billing pulses?
- Does anyone (ex-Tytel) know how to fiddle s/w in my phone to
- make it smarter in calculating bills?
-
- thanx
