This was a very good meeting. Jonathan (Joe) Roper, the Commercial Director for Star2Billing S.L. and Areski the A2Billing developer and project leader presented their Open Source Asterisk based multi-tenant system solution. They took us from the O/S through the install and application features level. Areski even gave us a peek into the project's future.
Thanks to Joe and Areski for staying up until 2:30AM Barcelona time to make this presentation!
