How do you sell your software when there is no page on your site for making a purchase?
It is impossible to know in advance a potential customers requirements.
For example some people might want Kamailio, Database Replication, Multiple POPs in different Countries etc etc.

So the idea is that any potential customer would make contact with us, we get an understanding of their requirements and we provide a formal quotation.

@phonesimon We recently went with CGRT and I can say it is AWESOME!!! @ewsamuels is a great guy to work with very knowledgeable about his product and FusionPBX. We have had many requests to add different things to accommodate our workflow and he usually has it done in a matter of days. The LCR alone is worth the money. Give him a call and get a demo. I still haven't tapped into all the feature of the system. He is always making improvements. He takes his customer suggestion seriously and tries to implement them into his system. Which makes it a better system for everyone.

Can anyone compare this to ASTPP. I am using that now. It does what I need but now I want to integrate with Fusionpbx. Not really an option with ASTPP. I thought about creating a frankenstein by mashing together ASTPP and Fusion but that looks like a lot of work.

Can I customize it or is it all obfuscated? It has an API which is good but sometimes API's don't do everything needed. What language is it written in? What DB does it use? Is it designed to run on the same server as Fusion or separate?

Daz, are you still using this as your billing platform? Just curious.

Maybe I'm just getting dumber in my old age, but I've looked at several billing platforms that are out there besides CGRT and there is one thing that I just don't understand. Software like A2Billing, ASTPP, Magnus Billing, etc. all include Class 4/Class 5 softswitch functionality. How does that play alongside FusionPBX if you're using FusionPBX as your switch? In my way of thinking, if you plan to use FusionPBX as your switch, wouldn't you want purely a stand-alone telecom billing platform where you import CDR's, rate them and spit out invoicing?
