They do have a non-managed $15/month plan (that still includes ztdummy 
and friends), comparable to what you get from vpslink at $15 -- however, 
they do not have a $8/month plan like vpslink.

I haven't done it myself, but apparently there are recommendations to 
open UDP ports 10000-20000 to your PC. I wouldn't.

Is it possible the Sipura uses UPNP or something to punch holes in the 
firewall itself?

Is it possible that they both use the same UDP port (e.g. 5000 or 5004), 
and for whatever reason the sipura gets the packets sent to your softphone?
