Frequently, i give some information to asterisk users, in their forums about the existence of Kazoo as an excellent alternative, typically when they have issues on their asterisk installs. Most of them don't know about Kazoo Platform and they resist thinking about a new learning curve.
On some of those forums they forbid me to talk about alternatives, may be to avoid losing customers and so on. Anyway i am finding out some other methods and also would give them a tour about migrating to kazoo platform.
