i have since double checked and found something interesting

from pstn access list, i know which network provider each pstn access number is coming from. Whenever i use those listed with LES.net, all calls fail. with LINK2VOIP, 100% success. Some are iffy: Callcentric or Voicenetwork - they don't fail 100% of the times but do fail.

I have to stress again that I am NOT behind NAT.

At this point I don't know who to approach to investigate this issue. My voip provider? Sipbroker? Les.net? Who exactly is responsible for call drops?
