Hi all.
I need help about ATA 188
We are testing VoIP with two ATA188 devices.
Each device is connected at customer side into internal network but at another country.
So communication is going from ATA in one country
to ATA in another country. All comunication is going
through IPsec tunnel.
My questions are : Is it possible connect two ATA devices through IPsec?
Is it necessary use voice gateway with devices, for example router which understand H.323 protocol?
Which ports shold I permit on access-list?
I mean both, tcp and udp and source and destination.
Now both ATA are running IOS H.323 and it is possible ping each other.
every advice will be deeply appreciated
thanks
jl
