A2Billing Customization | Experts Only!

I need small customization to the A2billing trunk section. 1. Auto switcher off based on ASR and ALOC data from a2billing. Example "If ASR and/or ALOC below 20% and lower than 60 seconds that specific trunk need to be unavailable and further calls needs to go to the failover trunk which was specified in primary trunk." There must be a page where this information can be entered like 20% ASR or 60 seconds ALOC. 2. Trunk daily limits. Example. "Daily limit for one trunk to process a minutes are 1000 minutes if trunk reaches that limit trunk should be unavailable for further calls and call needs to go the failover which was specified in primary trunk" 3. Pause between calls to the trunk. Example "Pause between calls to the trunk, if we put 60 seconds pause to that trunk no incoming calls should be sent to that trunk within 60 seconds after the call was completed and it will count 60 seconds after every call and if call comes but trunk in pause mode than call need to be redirected. Please start your bid with "hello world". so I'll be sure that you have read my requirements and you are not merely another freelancer bidding blindly. Good luck :)
