sbiddle:chevrolux: We have a Vodafone DSL connection in our office used just for testing. Most of which is SIP traffic and a lot of it goes to 2Talk.
Just RDP'd in to my work machine and get a very consistent ping to 2Talk. I think you have some internal network issues/congestion causing packets to be dropped.
Issue is widespread. Possibly related to an earlier fibre cut in Auckland.
So thats what i tripped over when John and i went wandering.
