Re: Can I ring my own landline phone? [Telecom]



The material below is not too helpful, I guess. You can try searching the

Q: How can I find out what my own phone number is?

A: If the operator won't read your number back to you, and if you can't
phone someone with a Calling # ID box, there are special numbers
available that "speaks" your number back to you when dialed. These
numbers are quite different from one jurisdiction to the next. Some
areas use 200 222.2222; others just require 958; still others 311 or
711 and others have a normally-formatted telephone number which can
be changed on occasion (such as 997.xxxx).

Such numbers exist in many countries; 175 is one number in the UK
while 19123 is one in Australia. There is no general rule for the
format of such numbers. These are normally assigned to codes outside
normal customer number sequences, however.

In areas where Caller ID is available, one could arrange to call
someone with an activated display unit and have that called party
read back the caller's number.

Q: Are there other kinds of test numbers used?

A: Yes. Again, space (and available information) does not permit a complete
list of what each telephone company is up to in terms of test numbers.
The most common number is a "ringback" or self-ring test number. When a
two or three digit number is followed by all or the last part of your
phone number, another dial tone occurs. Tests for dialing or ringing may
then be done. The ringback methods in some jurisdictions will vary.

Other numbers include intercom circuits for telephone company staff, or
switching centre supervisors, or other interesting tests for call
supervision or payphone coin tests.

One famous kind of test number belongs to NYNEX, the regional Bell
telephone company operating in the northeast U.S.A.. In New York at
least, there are "9901" numbers, or local numbers of the form xxx.9901,
which result in a recording which identifies the exchange represented
by the first three digits. The 9901 numbers may not necessarily exist
for all combinations of first three local number (central office code)
digits.

All these tests and services vary with each phone company; they are
not usually found in the phone book, needless to say.

I have searched everywhere but I can't seem to get an answer one way or the
other. There used to be ways you could test your landline telephone's
ringer. Any suggestions?

Thanks, pflu
