Well of course --- the issue I'm identifing is the overhead of an idling skipe node which establishes p2p links with every node it expects to communicate with vs sip making the one to the server
Do these extra connections really count as "Network Unfriendly"? How does it compare with the extra load on a meshbox due to the Asterix module? Well how about Skype being network unfriendly --- It makes direct connection to every peer you add to your phonebook, whereas Sip only connects to a server?

No I'm not sure, but I remember reading something like that. If there is no priority or bandwidth allocation given to voice traffic, I wonder how a voip conversation will survive when a few other users on the same node are downloading a CD at the same time and all trafic is FIFO...
