I have someone from cat.net.th on the phone and he doesn't speak a lot of E=
nglish and I don't speak any Thai..... He knew what indosat was and their =
AS number. He further stated he got my email (never told him who I was), b=
ut he said he would be replying ASAP. We only had one /24 announced by ind=
osat.
