MGCP? H323?

if SW are you 100% sure they're all made using G711??

have you tried resetting the CFBs?



if this helps, please rate

Sure it is not a barring issue, maybe they have configured so to block International conference calls- local regs ?

lkinchen Mon, 06/16/2008 - 07:22 I need to tell them to check the barring? what should it be?

I was more thinking it is a local barring issue on the CCM- Trunk to trunk allow for international calls
