Contrary to portrayal in "Enemy of the state" police haven't caught anybody yet though. Usually it is some poorer european nation state or chinese IP address trying to fraudulently call an african premium number. If such a call is actually made, I get the MP3 recording from that by email as well. Otherwise it will send me an email and answer with the voice of a slightly crazy Florida man, inquiring who is it, in a loop. But this context will just look if you are actually trying to reach one of my legit numbers and ring the correct phone even. And just remember that actions you take can have $ or annoyance consequences (how to test dial plans for 911 / 999 properly for example).Ĭoncerning security, I even run with allowguest=yes and context=incoming_guests in sip.conf. View it as something you need to spend some time to learn the ins and outs of and it isn't going to come together instantly and you will be fine. I was able to port old cell phones to Twilio easy and I can do SMS messages using their API and SIP trunk calls on the same numbers. Of late I have been using Twilio for my SIP trunks and they are great and inexpensive. I have heard horror stories that the phone company just laughs at you and you are SOL and on the hook for whatever bill they rack up if that happens. You need to be SUPER careful to lock it down from the internet however - it does not take long for scanners to find an opening and then hack in to make international calls 24x7 until you shut them down. I still use the same hardware today but it has grown to cover home lines, the home office + satellite offices for work (all connected via IPSec) and it "just works" once you put the time in to set it up and understand how to configure it properly. First set it up at the home office and tried various hardware to settle on Sangoma interface cards (the Digium cards were a mess back then) and Polycom phones then when the day job moved locations I set up a box with Asterisk a Sangoma PRI card + analog card for the fax line to support the whole office of 50+. I have been using Asterisk for over a decade now.
