<DIV><FONT face=Arial size=2><SPAN class=796163918-04012007>Since December the
1st we noticed a large increase in the amount of wrong numbers received at the
CC platform.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=796163918-04012007>As this problem
arrises once the call is established and there is no RTP relay I don't think is
a SER question but I resort to your major knowledge to see if someone can
enlight me about where to look to solve the problem. BTW. No changes were made
in the equipment at neither end.</SPAN></FONT></DIV>
