extra digit
Steve Lenagan
I own some answering services and we use DID circuits. One block of
numbers is xxx-5400 thru xxx-5500. We routinly get wrong numbers in the
55xx portion of the block. After a while I realized that when the
customer dialed xxx-5123 for example it would show up on our terminals
as xxx-5512. Some where the CO occassionally inserts and extra 5 after
the exchange number. We know its not customer equipment becuase it is
random and never repeats and some callers have said they used speed
dialers.
The telco (MTS) said, of course, our equipment is fine and ignore the
problem.
Any ideas?

This sounds like something I saw about 15 years ago. The answer turned out to
be that the call they were trying to place was to, say, yy5-5123, but was a
toll call; they had not dialed "1" first (required in that area, even within
the same area code); and they were calling from the same exchange as the wrong
number which rang.
The logic went something like this (badly expressed, but bear with me):
- switch sees first digit, says "OK, that's quite possibly local".
- switch sees second digit, says "Yup, that's good too"
- switch sees third digit, says "Ouch", somehow dumps the call back into
itself *to the same nxx* but then processes the third digit dialed as part of
the last 4.
Bizarre, eh? It finally went away when they upgraded the switch locally (this
was back in Ontario).
Seems unlikely to be the same thing, but the symptoms sure sound familiar...

I have an 800 number that is almost the same as 1-800 MERRILL for Merrill
Lynch. I am regularly getting calls from people who dialed two E's by
mistake (1-800-MEERRIL). I think that a lot people have dirty contacts on
the keypads, or stuttering fingers. If it really happens with speed dials it
may something else, (but my experience with people reporting telephone
trouble is that you can't always believe what they say they think
happened...).

Put a touch tone data logger on the line and capture the incomming digits,
when a "bad call" is recieved have your opperator log the time and go back in
the log to find the call and check the incomming digits. dr.d Kiss

Just for jollies: verify your loop current and line voltage on ALL DID
trunks. My bet is that you have a hot one that is "bouncing" or echoing
a digit. I've experienced this with voice mail receiving DNIS steering
digits. I've also seen this on semi-hot trunks with load coils inline.
Good luck!

The problem is not faulty caller equipment since it is never repeated from
the same caller.
The problem is not in the DIDs since the lines are all conditioned and the
problem is only in the 55xx group. We have 54xx and 08xx and experience no
problems. Our DID equipment has never logged a call outside of those
numbers so we know the problem is ahead of our connection to the CO.

Hi. I do tech stuff for about 60 answering services all over the
midewst and I'm well acquainted with most of the vendor's systems
and their various tricks. Here are a couple of questions for you:
1) Are the wrong numbers always showing up on the same trunk?
I know you said they show up on different accounts, being called
from different places. But is it isolated to one trunk?
2) Which TAS equipment are you using.
3) Are your DIDs using DTMF or dial pulse?
4) I am assuming 4 digit feed. Is this correct?
Here's something I ran into once a few years ago:
DTMF signaling which was too loud, echoing, or distorted.
The incoming tone was on the raggedy edge of detection, then dropped
out of detection, and then back in, all withing the duration of the
one tone. The decoder in the TAS system saw it as two tones. Even
my stand-alone touchtone decoder didn't find this at first, since it
had a better decoder than the one in the customer's StarTel.

Appears on all trunks and is isolated to only the 55xx series. 54xx and 08xx
are unaffected. We also have a DID paging system on 78xx and 79xx blocks and
the problem does not occur there.

Correct

The lines were checked with a HP 4935A. We have out grown the last 3
locations and have had this problem in every location.
