Hello all,
I'm an IT guy working for a mid-size company. I got to admit that I
don't know much about telecommunication stuff. My company is using a
NEC NEAX 2000 phone system, and my assignment is to write a phone
accounting software package... So I contacted NEC and get their SMDR
data format spec... Wrote the program... Now the software is complete
and in beta testing... The only thing that I found not working right is
the station number in the SMDR record not matching the actual extension
number. For example, a station number 110 in SMDR data is actually
mapped to phone extension number 119, while the station # 119 mapped to
another extension, say 130, and so on. They don't seem to follow any
patterns.
That is an interesting behavior that I've not seen before. I've
worked with a couple NEC NEAX 2000s to watch the SMDR and the
station was always the extension. Nearly all switch vendors seem
to define the words station and extension to mean the same thing.
A few prepend some data in the case where there are special dialing
plans in place.
My questions are, what exactly does the station # stand for? Is it
different from the actual phone extension number? If so, how are they
related together? When a new phone is added to the system, is there any
way to assign the station number and/or extension number to that new
phone? (Or how do new phones get added to the system?)
If I can find the relationship between station number & extension
number then I can modify the program to use extension number instead of
station number.
Thank you for any inputs.
VHD.
Your best bet is to talk with a switch technician about a specific
switch that you are having problems with and ask what tables are
involved and what the SMDR contains. Perhaps there is other
informatino that you can use to resolve your problems.
Are you perhaps confused about which phone is indicated by the
station field in the SMDR? Okay, I think I 'see' the problem.
Normally an SMDR station indicates the originating phone in a
call. You may also need to look at the accounting code (not
sure of that name) to se what information the SMDR contains.
For instance, many switches will change the SMDR.station to
another value in certain circumstances. Consider a call to
a phone that isn't answered and is autoforwarded to another
phone that is picked up. There will be several SMDRs generated
and only the first SMDR could have the originating phone.
The SMDR Specification for your switch may specify what the
expected behavior should be.
Good luck,
David
