I have installed an Asterisk server and tested it succefully to work with two users using softphones.
Now i want to make calls outside? with a little search over internet, i find those solutions:
-to have an account with a sip operator
- connect to the PSTN
i opted to use the second solution, so here is my question: is installing an FXO interface on the server the only solution? is it possible to use a “gateway” to connect my server to the PSTN? if yes does an ATA do the job?
