RE: [Asterisk-Users] Billing (itemized) in the UK
Pete,
I am also in the UK and I have added an include in my extensions.conf for
the file listed bellow.
exten = _15X,1,Dial,${TRUNK}/BYEXTENSION
exten = _147X,1,Dial,${TRUNK}/BYEXTENSION
exten = _NX,1,Dial,${TRUNK}/BYEXTENSION
exten = _01.,1,Dial,${TRUNK}/BYEXTENSION
exten = _07.,1,Dial,${TRUNK}/BYEXTENSION
exten = _08.,1,Dial,${TRUNK}/BYEXTENSION
exten = _09.,1,goto(nogo,1)
You dont need a 9 for a line, you couls also add lines for barred numbers
Regards
Dave

Subject: [Asterisk-Users] Billing (itemized) in the UK
Thank you very much for the answer! I think it is a good path to look at. I
have had a look through
our paperwork for the present pbx, and I found one document that seemed to
indicate we have to dial
1666extndialled_number
to give the extn info to the telco. The paper is a bit old (1999) and since
then we have changed our
telco, but I guess that this protocol is still valid. This afternoon I will
hook up a recording
device on the line and see which digits are actually dialled when I dial an
outside line. From the
recording I should be able to reconstruct which digits have actually been
dialled by the pbx.
If the protocol is correct, I could construct a dial command such as
exten = _9.,1,Dial(Zap/g1/1666ID${EXTEN:1})
or so - I would just need a way to construct id - and then any caller from
an inside device would
just prepend a '9' before the real number. I probably would also bar simple
'9' dialling to get an
outside line... lets see.
Keep you posted, and so many thanks for all the help!

Hi Peter
You need to first of all ask your Telco what mechanism it uses with your
current switch. The most likely ways are
1) Two stage dialling. 1xxx pause PIN exten dialled number
2) access code1xxx exten dialled number
You need to get the specs for this from Your Communications. It is not
clear from the web site...
Asterisk will cope perfectly with either solution - you will just need
to fiddle a bit with the dial plan. Once we know what you have to send
to the telco there are tons of people here who will advise on the Dial
command you should use to achieve what you want.

Hello!

Is there a standard for sending extension numbers (i.e. do I have to

RE: [Asterisk-Users] Billing (itemized) in the UK
You just need to do something like
exten = _9.,1,Dial(Zap/g1/1666$CALLERIDNUM${EXTEN:1})
You can also do some useful translations like
exten = _9[2-8]XX,1,Dial(Zap/g1/1666$CALLERIDNUM0113${EXTEN:1})
This will look for 9, then a local number beginning 2,3,4,5,6,7,8 , and
dial out the extension number, followed by the 0113 area code.
You will need to make sure that 999 and 112 go direct to BT by using
another line in the extensions file. E.g.
exten = ,1,Dial(Zap/g1/999)
exten = 9112,1,Dial(Zap/g1/112)
And probably
exten = 999,1,Dial(Zap/g1/999)
Just to be on the safe side!
You could also write a little macro to kick another user off their call
to allow the emergency call to get priority.
There is just so much cool stuff you can do. But do test well!

Re: [Asterisk-Users] Billing (itemized) in the UK
Thank you very much for the answers - I have hooked up a special adapter and active loudspeaker on
each of the three BT lines, but when I got a line and dial a number I cannot hear any other digits
than those I dial - I would have expected something like seven DTMF bursts/digits (16662xx) before
my digits are audible. Near the pbx I have noticed a small white box saying 'Smiths communications'
and 'SC14' on the lid. The box is connected to two cables - one to a power supply, the other is a 4
pair telephone installation cable with 3 pairs connected. Next to the box is a switch with some
labels on it: one label says 'LINE 1'. The other two labels describe the switch settings - 'SYSTEM'
and 'A/PH MOD'. I have the suspicion that the white box has something to do with the billing and
that it sends some fast data over one of the lines when an outside call is initiated, but I am not
sure. I'll continue to hunt.
I also asked the telecom provider but they were not very helpful and couldn't
(or didn't wish to)
give me any information as to the technical details.
I'll hunt on...

Re: [Asterisk-Users] Billing (itemized) in the UK
Solution found!
I connected a recording device to the line and called the same number (near London) from different
devices. The recording I played into an audio editor (cool edit) and played the files with a program
that could decode DTMF signals. The program then showed the numbers I dialed. Except for the
recording from one or two devices (missed digit / double digit = audio not clean) with every
device the dialled number was:
1666wwwstation_idwdialed_number
The first tests failed because I tried a local number and we have least-cost-routing as well, so
that 1666 only works with non-local numbers.
So many thanks for all your help, esp. Tim Robinson's comment which brought me on the right track!
Also for those who gave me different dial commands - I will look into that. We should now be able to
connect asterisk to the PSTN line and still get the itemized bills from our telco as before.
One post asked why we wouldn't move over to ISDN - the reason is that our analog lines have so far
sufficed for us in every respect and I try to follow the maxime: If it ain't broke, don't fix it.
