Instant messaging/VoIP project

[galapogos]

Hi,

I'm trying to get started on an instant messaging/VoIP project that uses a client-server architecture, and I'm thinking of looking at open source projects such as Jabber to understand the underlying architecture. I've had a bit of network programming experience more than a decade ago but haven't done it since (more of a firmware programmer the past few years).

The end goal is to have a full featured server setup to handle IM/VoIP and mobile clients (Android/iOS/etc) that supports secure calls/IMs, groups, and other cool stuff, but I'll start with a basic IM infrastructure (server-client) first.

Does anyone have any recommendations of which open source project I should start looking at first, as well as any relevant tutorials/guides/forums for IM/VoIP development? I'm looking at ejabberd for the server side as it uses XMPP standards and has Windows/*NIX/OSX support, but it uses erlang which I'm not familiar with (I speak C/C++ and some Java)

Thanks!

Hi,
interesting project , you should make the server and clients for VoIP and instant messaging secure and reliable , to underst. from several layers ( points of view ). Today we have a lot of open source.
try out
http://www.linphone.org/
http://www.voip-info.org/wiki/view/O...+VOIP+Software
http://en.wikipedia.org/wiki/Compari..._VoIP_software

I had an idea to make something close private server and client + protocol modification , but it is long job + budget + need to relocate to work in comfort place.

Kindest Regards,
