Yup. There is other stuff like attaching call logs to a contact.

a) if the VoIP client supports some native URL scheme, it would be best 
to
    invoke that by the dial link, like:
      sip://12881727112/
    don't know whether something like this exists.

b) The dial out is a bit more complicated than just making the server 
make a
    connection. Keep in mind that you have three devices, the 
browser/server, the
    actual phone (or software) and the PBX.
    Dial out need to make the PBX connect both source and target phones. 
This is
    supported by TeamCall, but I have no idea about Asterisk.
    (you basically need two phone numbers, the target _and_ the source)

Yes, could be a small Java Applet which triggers the browser. Nothing 
impossible and I suspect something like this should be already 
available for Asterisk.

Yes, that would be a good starting point. So we need to have some 
research on that Asterisk protocol to connect two phones.

Dial-In is not supported. As you correctly analyzed this is not really 
possible for a pure HTML interface.


BTW: if someone with Asterisk knowledge/experience wants to do that - 
we could setup an asterisk.opengroupware.org server which hosts a 
testing/integration environment for OGo developers. We would need to 
find someone wanting to setup/admin Asterisk on an OGo dev machine.
