Hello
i am using A2billing 1.9.4 with asterisk 1.4
i downloaded a call shop software that gives 10 day trial before purchase. (
http://callshopbilling.com)
I did the installation as indication in the manual of the software. and i created a new customer in a2billing to give a try.
while configuring the calls shop software i am able to make a test call with a2billing directly. But when i try to make a test call with the booths that the call shop software create it gives the following error that "proxy authentication required".
i will be glad it someone knows how to configure sip settings in a2billing for this software
