I got a call from an overseas call center telling me about the
problems with the Windows machine I was using. They wanted to remote
in and fix things for me ... (Ignore the fact I use a MacBook Pro or
an ASUS laptop with Debian).
This is a common scam scheme.
Try "windows scam call" at YouTube.
Whether CLI spoofing works depends on the provider and has not so much
to do with Asterisk. Asterisk makes it possible, but so does every
common SIP softphone or most other SIP device for that matter. If the
CLI you claim to own will get actually transmitted to the callee depends
on the provider you are using for termination and whether they allow you
to set an arbitrary CLI. It also depends on the routes that the call
travels through until it reaches the callee. If there's a "grey" route
on the path that overwrites your CLI, such as a GSM gateway, your CLI
won't make it to the callee. Nowadays you can find providers that allow
you set arbitrary CLIs on every corner.
