[Asterisk-Users] Credit Card machines / interop

[Linus Surguy]

If you do it with SIP and G711 you are probably OK. The protocol used for 
the authorisations is only 300 baud (in the UK) so shouldnt be a challenge, 
but IAX somehow still manages to mess some of these up. However, the unit 
will also be polled by the bank to collect the payment file overnight, so 
you'll have to handle incoming calls too.

In my experience though, it is better all around to leave the data devices 
direct to the PSTN, much less headaches/hassle.

Subject: [Asterisk-Users] Credit Card machines / interop


Hi all,

One of the areas I am trying to research before I can confidently start
deploying Asterisk is "Credit Card Machines". (PDQ / Streamline machines
/ any similar)

I'm talking about the credit card swipe boxes at point of sale desks.  I
believe they dial out to the specific bank provider everytime a card is
swiped.

My question is:

- Does anyone have any experience using these type of devices with
Asterisk, possibly with a SIPURA type SIP device.
- If not, is my assumption that at the very worst I will just have to
connect them to a FXS port on the * and that should let the device break
out onto the ISDN E1 line?

As always thanks for any insights / advice people can give.

cheers

alex

Dear Friends of Ubiquity Software:

As you may have noticed, Ubiquity Software began using the web domain 
ubiquity.com earlier this year in addition to the previously established 
ubiquity.net for our website and email communications to you.  However, 
since that time, a dispute has emerged with respect to actual ownership of 
the ubiquity.com domain.

As an international software company founded over decade ago, you can always 
reach Ubiquity Software under the website www.ubiquity.net 
<http://www.ubiquity.net/>  and via email at @ubiquity.net.  However, we 
have also chosen to expand our domain to the more specific 
www.ubiquitysoftware.com <http://www.ubiquitysoftware.com/>  for web and 
@ubiquitysoftware.com for email communications.

Please use either the historical ubiquity.net or begin to use the new 
ubiquitysoftware.com domain for all email communications to Ubiquity 
employees from now on.

Thank you.

Regards,

Ubiquity Software
