Hello, I thought this would be the right time to let everyone know we are going to release open source billing for FreeSWITCH. Completely developed in PHP/MySQL. Some of the major features includes: Both Pre-Paid and Post-Paid model Multiple administration access levels Multiple reseller level Easy rate/price management Route management Separate user interface to view their CDR(s) and billing information Authentication by IP/ANI and SIP registration Codec management for both user and switch CDR statistics Gateway statistics Admin/Reseller/User management Switch management from 1 GUI Balance and payment information ... and much more. We need volunteers for testing. Please drop an email --[ vbilling [at] digitallinx.com ]-- if anyone is interested. Thanks.
