[Freeswitch-users] FS and Billing, AGI emulator

Hi, I wanted to use A2Billing on FS, but I noticed it uses some AGI stuff for dialling and to check how much credit the user has, etc. I heard you could use A2B by just importing the FS CDR data into it, but that wont work, so I come to the conclusion that I have no way of doing billing on FS yet. There is ASTPP but that's not complete yet, and I heard vague comments of doing an AGI emulator on top of the event socket on FS, how hard that would be? Is there a possibility to do that? How much would it cost? Thanks, Diego
