Drop Asterisk, move to Freeswitch. Much easier to interact with external code bases, and it has more than one language interpreter built in (javascript, lua, etc.). If you're intent on staying on Asterisk, I would suggest skipping AGI, and write a client that monitors the state of asterisk via the manager interface. AGIs are messy in my opinion. There isn't really any best language for AGIs, as AGIs just communicate with Asterisk via a pipe. So really, the best language for AGIs are the language you like the best and/or best fits the application domain/requirements for your project.

AGI and AMI are 2 different solutions to 2 different classes of problems. It may even make sense to use AMI in an AGI. I've never had the need. AGI is executed in the context of a call. AMI is completely external to a call. Think of AGI as dialplan on steroids and AMI as SNMP. AGIs are messy in my opinion. AGIs are very clean in my opinion. AGIs solve a large body of problems. An AGI is executed when requested by your dialplan. It does something and then it exits. If the caller hangs up, your AGI is notified (via signal) and can do something about it. If your AGI crashes, it only affects that single call. If you have 2 simultaneous calls, you have 2 separate AGI in separate processes and memory spaces. AMI implies writing a daemon that must be running all the time. Almost by definition, it should be multi-threaded or event driven so it can handle multiple simultaneous calls. If the daemon crashes, it will probably adversely impact all calls. AGI and AMI are only 2 tools at your disposal. In terms of ease of implementation, I'd define the available set of tools and rank them in this order when considering how to solve a problem: ) Dialplan ) AGI ) AMI ) Asterisk applications The list would be inverted if you consider complexity (skills needed to write) or risk (impact of a bug). There isn't really any best language for AGIs, as AGIs just communicate with Asterisk via a pipe. So really, the best language for AGIs are the language you like the best and/or best fits the application domain/requirements for your project. As Bill Clinton would say it depends on how you define best. What is appropriate for 10 calls per day may be different than 10,000 calls per day.

I think of AGIs as little black boxes that hide complexity and allow the dialplan to remain simple and robust. Pbx_lua and ael are the next logical extensions to dialplan(?) My guess would be AEL then lua, but it's just a guess. I'm starting to use AEL in 1.2 -- syntax checking sux and inconsistencies abound. I'm hoping AEL has gotten better. AGI can be simple custom code in PHP, Perl, C, etc. AMI is like AGI but using Manager interface... AMI is not like AGI. They have similarities -- AGI talks to Asterisk via a pipe, AMI talks via a socket. Both can be written in any language. (Actually, both are just protocols, so using them as nouns is just a shorthand for a process conforming to the [AGI|AMI] protocol. But, they are different tools for a different set of problems. AGI focuses on a channel but can interact with Asterisk as a whole. AMI focuses on Asterisk as a whole, but can interact with a channel. AGI executes in response to a action in the dialplan (calling AGI()) and it's lifespan is (usually) a subset of the lifespan of a channel. AMI executes either as a daemon or in response to a process external to Asterisk -- like a web page or a program executed from cron. I've never used AMI for anything other than simple stuff like please reload or how many channels are active so I could be all wet here. and Asterisk Applications is tweaking, patching or rewriting the native C code?? Yes. This is where it gets fun -- a simple programming error can crash Asterisk -- taking all in-flight calls with it.
