I want to prevent un-authorized directing of voip calls to my 5300....
I have an AS5300, doing voip termination to the LD PSTN..... I have other 5300s pointing at it directly... so my gateway IP Addr has been handed out a bit too much...
I think a Gatekeeper (w proxy) may be the answer,
but I find no gateway config samples on the CCO/TAC sites....
or it 'feels' like H.235 may be an answer....
how do I configure a gateway/gatekeeper pair such that other 5300s cannot point directly at my 5300, but must enter thru my gaekeeper or whatever....
Thanks,
Rich
