That is the big advantage when you compare it to SIP. That’s because the protocol design is completely different: it is P2P with Nodes, and can access everything everywhere. It just works, there is nothing, nothing to configurate at all, it juts works.
They do not have these problems, they work out of a box. Let’s have a look at the other side: Skype, the working solution everyone knows, and Jingle, the hopefully-somewhen-to-be perfect solution. And that’s the fault of SIP which is designed in such a way. Especially when there is a NAT setup with more restricted rules on both sides SIP is impossible. In other cases, you have to start dealing with STUNNEL, UPnP or similar stuff – and that does not work in every case. The problem with SIP is that it only works out of the box when you have either no NAT-Router or Firewall at all in front of you, or if you have SIP capable Firewalls/Routers. And SIP is not a solution which can be compared with Skype. In fact, they cannot but introduce even more problems. But I also have to say: They do not solve any problem. Thanks about the comments and the hints, I really appreciate feedback here. Especially Jingle and Skype is something I think about quite a lot.Īnd everytime I blog about one of these, some user point to to some SIP solution like Wengo, Ekiga or Gizmo which are supposed to solve all my problems I have with skype (not standard compliant, until some weeks ago no Alsa support, etc.). Once in a while I blog about some VoIP stuff.
