Hello SIP Community: I'm starting to read and understand? DLNA Remote Access? (RA). Key to understanding it is understanding SIP/SDP/ICE/STUN/TURN, all of which are new to me. My question is, are there service providers (world-wide) that host SIP proxy servers that can be used on-demand? Can they scale on demand? Could you name a few? Are these SIP Proxy Servers globally federated, i.e., they know the how how to send the "initial ICE offers" to the peer. Any pointers from this community would be very helpful. Thank you.
