Hello everybody. I’m new on Asterisk and this forum!
I would need to know if this setup is possible with Asterisk:
A softphone in a remote country (say, Mexico)
place a voip call
to an Asterisk box (say, in Italy)
which provides the client a local (“italian”) dial tone
to place a “regular” pstn call.
I figure out that the Asterisk box has to be:
a) permanently connected to the internet and have a known, public ip address
b) connected to the pstn via a pci FXO card known to be compatible with asterisk
c) configured to automatically answer to the incoming voip call and connect it to the pstn
d) pass or “regenerate” the DTMF tones generated by the softphone and make sure they are understandable by the network
Are my assumptions correct?
Is this setup common or…“esoteric”?
Does it poses a fraud threat, eg. someone discovering this service up and running and placing free calls to the pstn? How can I mitigate it?
How much guaranteed bandwidth does it needs?
I would really appreciate your help.
