webwat: Ask your ISP if they can get telecom NOC to investigate the congestion, there may be some interim fix they can do.
Thanks Webwat,
Two people from Xnet have responded to my issues on the Xnet forum http://www.geekzone.co.nz/forums.asp?forumid=65&topicid=81800 (after getting no response from the helpdesk for 6 days) and have said that "your backhaul issue has been escalated to Senior Technical Support at Telecom Wholesale and I've requested an update on the situation"
They have also said that by default my service willl still be on BUBA (not EUBA) after the ADSL2+ upgrade in September. Does this mean I'll still be using one of the the 2 Meg backhauls or the Gigabit one?
I still can't understand why another customer on the same exchange has no issues with VOIP quality and I do?
Regards Allen
