Want to integrate my cellular service into my asterisk dial plan, so this requires SIP capabilities such as one can get with Vitelity vMobile. Does Google Project Fi or Ting or another offer a SIP integration option, but not advertise it?
A drawback with Vitelity vMobile is that it will not complete a 911 call when just on WiFi. So if your remote cabin has internet, but is in an area without cellular service – or if the cellular antenna sat on top of the World Trade Center – you can not call 911. Otherwise, i really like Vitelity.
Like Google Project Fi, vMobile will uses the other phone number associated with the phone – the MobileDirectoryNumber, not the DID nor MIN. Meaning the 911 call center will see a totally different phone number than what you remember your phone to be. When it comes to this, vMobile using the MDN idiot proofs the sip setup.
Wish all firmware would automatically send a TXT message to 911 with GPS
coordinates every five minutes or so. Yes, most 911 does not receive TXT
messages yet, but becoming more common. Possibly use text-to-speech to announce location into the phone call.
911 is hard. A recent tour of a local 911 call center showed 911 systems are way out-of-date and proprietary.
