All these SIP phones may very well be able to do SIP-to-SIP calls to each other, but whether a particular provider allows peering from its own network depends on their business model. You can be just as tied to them as you are with Skype. There is nothing in the specification of the SIP protocol which mandates they must allow SIP calls to other networks through their network. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
