I have two customer. Both connected to Internet (ADSL)
Each customer has an IP fixes and an equipment with ATA 186. The configuration would be:
Customer 1: extension 1000 Customer 2: extension 2000
When client 1 dialing 2000, they call to VoIP phone of customer 2 ... and vice versa.
This simple configuration can be made without having to use a Gatekeeper (Asterisk, CallManager, ...)
The solution seems to be in that ATA of customer 1 puts as gateway ATA of customer 2, and vice versa.
I was not able to find answers in the Cisco documentation.
Would know somebody like doing it? Would you have any url/link that explained it?
I really need help. Thanks.
