Re: AMI or ARI?

We made a predictive dialer for some clients, our stack is based on Python, AsyncIO, API-Hour and Panoramisk.
Instead of AMI, we use dialplan and FastAGI to track calls, because it's easier to have a context and to be async and multi-worker in the same time, for the best performances.
We made a lot of daemons with AMI only, it was often complicated to track calls, even with CEL events and linkedid that helps a lot for that.

I don't know if node.js is multiworker, however, it should be enough efficient for a size of callcenter like that.

About AMI/ARI debate, AMI should be a little bit more efficient that ARI, however, I never benchmarked that.
ARI is more consistent and if I understand correctly, some stuff are possible only with ARI.
If you have no existing code, you can start with ARI easily.

Have a nice week-end.

Hi, 

I like to develop a predictive dialer system (Web base) to allow Admin to create outbound or inbound campaigns

I'm doing some technical research and I am trying to figure out shall I use AMI or ARI? 

- Creating many outbound calls and monitor live calls on the web (Ringing, Talking, Hang up their call)
- Originate many calls and put in specific queue (other word: campaign)
- Agent should be able to transfer a call - external or internal.
- Ability to set max ring time for each campaign
- Approx 300+ agents

On the browser, I would like to use websocket to get real time information about the call and actions.

I am considering going with this approach: create a daemon with Node.js - A daemon will connect to Asterisk via ARI and a daemon use websocket to listen the events and such. A browser will also use websocket to communicate with a Node.js daemon.

Something like that: <browser (websocket)> --- <Node.js daemon & ARI (websocket)> --- <Asterisk>

Is this good approach? 

Thanks
