Hi- I know how to install and configure freepbx/asterisk 1.6- I want to use a2billing for incoming DIDs via freepbx trunks to route to extension to PSTN PBX connected to asterisk server via sangoma card setup Dahdi channels.
then i want to do all the administration via a2billing/billing flate monthly rate for each incoming DID.. I have not installed a2billing before with asterisk/freepbx and I am seeing install guide but it is confuse me creating postsql database steps, can some some either email me step by step how install a2billing on asterisk1.6/freepbx running centos 5.0? Second if set up dial plans extension.conf do I have use freepbx to point DID to extension extension option .. and create custom- a2billing,1 {exten} ?
ultimate goal is user calls to DID# then asterisk send the to extension on another PBX such as mitel/bts switch then user extension rings.. lator on i will be needing these mitel extension to call outgoing and callerID is utilized not sure if a2billing support pinless IVR yet?
sorry to put too much need on this forum
