Hi List, Is there any open source application out there that provides an Erlanginterface for programming a voip router? Or is it the asterisk ecosystem(for instance with Erlang using AGI) that comes the closest to theoriginal mission? S. FreeSWITCH has two modules, moderlangevent and modkazoo, which present FreeSWITCH as a C-Node to other Erlang VMs. We built and use modkazoo for Kazoo, but it is generic in purpose; I know several folks using moderlangevent in production as well. Different use cases for each. Is there any simple description of difference between modkazoo and moderlangevent together with hints which use cases they are good for? ____ _erlang-questions mailing list http://erlang.org/mailman/listinfo/erlang-questions

Its been a while that I've looked at mod_erlang_event, but the main differences I recall are:

mod_kazoo supports multiple connections from multiple VMs; mod_erlang_event supports one.

mod_kazoo opens many TCP sockets for streaming events out of FreeSWITCH to the Erlang VM; mod_erlang_event streams them over the same connection as everything else.

mod_erlang_event allows you to take control during the dialplan processing; mod_kazoo does not. Both support being in control of the call from the start (similar to mod_xml_curl if you're familiar with that).

mod_kazoo runs more threads and seems more performant internally.

I would say (without having seen recent commit history) that mod_kazoo is a more maintained module with a company being behind it (2600Hz), while mod_erlang_event is more community supported at this point (again, could be heresy).

We built Kazoo on mod_erlang_event initially, but decided we needed to rewrite it from scratch once we hit a certain level of call volume; mod_kazoo is the result of that effort.

mc_:

mod_kazoo is a different approach than mod_erlang_event

we use mod_kazoo

it offers setting up separate TCP connections for event streams out of freeswitch
mod_erlang_event only supported multiple connections via DistErl by accident

mod_kazoo explicitly allows multiple connections there

and the new mod_kazoo offers even more good stuff over the existing mod_kazoo
