Well, i can't say whether it's properly programmed or not, but when i added 60 IP Keysets to the UGW card, it placed the IP Keyset ports ahead of the Media Channels. ie in the npl, the media channel trunks are now located at 0,1,60 whereas before they were 0,1,0.
I'm guessing the trunk group lost track of the ports, so it was dropped.
Anyways, thanks for the pm. I've got my first FlexsetIP up and running!
