Hi!

I'm trying to deploy IM service in my company based on ejabberd's jabber proto implementation. What I wanted to say is that ejabberd should fit all your needs. You shouldn't expect any problems with VoIP (video calls as well) as log as you have UDP traffic going between peers in your network without any restrictions (this is the RTP's by design requirement).
I don't think you will need STUN server since it's only necessary to determine "external" IP in case your peer are behind NAT. However, here you may face with some problems I didn't see when tested my installation since my network is based on routing and does not have NATs.

When you referring to Skype as VoIP standard you should keep in ming two things (of course this is my own impression after several months of investigation IM & VoIP services):
1. Skype became such notable mainly becuase those guys made it work everywhere not depending on client's network infrastructure.
2. Those guys wrote very good audio codec and that made the Skype almost the only software with such excellent capabilities to survive where all other progs just dies saying "damn, I've just lost the RTP stream, sorry... :(".

My conclusion after some time trying to make Skype replacement is that jabber currently isn't very good for corporate environment since it lack of supporting LDAP integration (yes, in general it does but for me and many others current level of support makes it unusable), auth mechanisms support and many management instruments that I have to script by myself or even patch the code. However this is one of the best jabber protocol implementations that has one killing feature that I didn't find in other ones: it is very survivable which is "by design" because it has been written in Erlang.

Thanks for reading this! Hope you'll find my thoughts usable and don't hesitate to ask specific questions about your type of ejabberd's deployment.
