I have been trying to figure out my problem for the past 2 weeks. And I am still at a dead end. So, I was wondering if anyone here have any experience with the issue I am having. I am using A2Billing 1.2.3 and trixbox 2.0.

Here we go:
Having set up my extensions(in FreePBX) I want to be able to apply billing to them using A2Billing. I want to be able to create an extension and then use a2billing or even use the DID option where I can set a flat rate every month for that extension and also be able to bill that extension if it makes international calls accordingly. I have tried all the possible website that Google brought up but none of them had any documentation of how to even go about configuring any .conf files or anything relating to this matter.

If anyone can help me I would really be saving some sleepless nights like tonight. Thank you.

This question may already be answered on the forum, but generally you want to set up all your extensions in extensions_custom.conf since freepbx does not rewrite this file. However if your internal extension are already calling each other then just insert "outbound-allroutes-custom" Here is a quick and dirty way:

; this will allow 7000 & 7001 to call each other without a2billing
[from-internal-custom]
exten => 7000/7000,1,Congestion ;congestion if ext dials itself
exten => 7000,2,Dial(SIP/7000,30) ;rings ext and times out at 30 sec
exten => 7000,3,Voicemail(u7000) ; If unavailable, send to voicemail w/ unavail announce

exten => 7001/7001,1,Congestion ;congestion if ext dials itself
exten => 7001,2,Dial(SIP/7001,30) ;rings ext and times out at 30 sec
exten => 7001,3,Voicemail(u7001) ; If unavailable, send to voicemail w/ unavail announce

; a2billing will ask for pin if 7000 or 7001 tries to dial any other number
; this context "outbound-allroutes-custom" is freepbx builtin
[outbound-allroutes-custom]
; this is to bill outbound calls from internal
