Asterisk Framework for call via Browser (VOIP and Chat)

First of all, I’m very interesting with this Framework. First look are very impressive.
Thanks for contributor which make the Framework so awesome.

However, there are a few question regarding the Framework it self.
Obviously we are looking Framework which can integrated with our existing VOIP System (Cisco CUCM v11)

We want to call directly through web browser instead of using soft phone (or any desktop based application). Is it Asterisk Framework possible to do that?

Moreover, is it Framework able call directly to PSTN or any extension that registered in our CUCM and receive call as well?

I don’t have any background in Network. I’m full stack developer and Software Engineer.

Last but not least, is it Asterisk Framework support for IM services? Like Spark Client Chat but through browser?


What APIs are you talking about?
