Packet 8 resellers continue to report problems with the network, with calls being dropped and the worst sound quality in their history. Something is up.
Another report has two of the top execs from 8x8 visiting someone in Kansas City the last month or so.
My guess is that the internal and network issues at Level3 are putting a strain on a few VoIP players, and that P8 is looking at Sprint as a possible replacement or at the very least as a supplement to what Level3 is providing them.
