Again, nothing new. I have already implemented this on my app here : https://play.google.com/store/apps/details?id=in.xtel.quitq.... using Twilio alone. But, twilio is not completely free.

Sorry, what's an SIP provider? I've looked it up and still don't understand what it is. Is it a residential service? Can anyone get it? Is it some form of VoIP? Or a classical phone line? I've seen it in multiple places but don't understand what it is or which companies it relates to.
Twilio, Plivo, etc.
Just pay the 0.02¢ or whatever phone services charge these days. If your business is actually big enough to have to worry about phone verification, do it right. Users don't like to call your number since they don't know the costs associated with it (especially international users). Furthermore, it makes number spoofing much harder.

It's the open standard for VoIP. It's used in many places, but mostly offices. An office might have an exchange system, with features like voicemail and routing different types of call over different networks. I have a personal account which gives cheap international calls, which I added to my android phone. I can receive calls at my SIP address, from anyone on any provider. When I make a call, I'm given the option o…
Hi, there's a free phone verification using facebook. It's account kit. https://developers.facebook.com/docs/accountkit/overview What do you guys think?
As great at this probably is, I don't think adding yet another dependency to facebook is a good thing. I'm getting tired of services that only accept facebook users. Having a facebook login or any other facebook service requiring the user to be a facebook user is not bad in itself (and can be pretty useful), but it should _always_ have an alternative. That's why I think projects like Dial2Verify Twilio are a great th…

Can you recommend one that works well? I want one that hopefully provides a Greek DID, I want to be able to make calls from my Android to landlines over my home Internet connection, as you describe, but I haven't managed to find a good (read: cheapish) provider.

Basically, because there is no verification/validation surrounding caller id - https://en.wikipedia.org/wiki/Caller_ID_spoofing
What's known as "caller ID" is just an add-on that phone companies glued onto the system to have a feature to sell to the public. Another such feature is ANI[1] which was originally meant for billing purposes but is a feature sold with toll-free (800) numbers. It is much harder to spoof, but even ANI is not guaranteed to be present. I would really love to hear a telecom engineer explain why the true origin info isn't…
The telco has some connection to a customer site which carries signaling data and N concurrent voice channels. A potentially large block of numbers are routed down that link by the telco. When he customer makes an outgoing call it sends whatever it wants (or nothing) as CID.
A national franchise with 1,000 stores serviced by 30 different small town telecoms might all send the national HQ number as caller ID, even though the calls do not jump through the national HQ first.
There is no will among the various telecoms to build and integrate a whitelist system that interoperates, so they leave it wide open.
You can't just find out who a phone number belongs to, and phone numbers do not have to ring to anyone on the other side to be valid outgoing CID numbers. It's unclear how such a whitelist system would help anyone, anyway.

I switched to a different SIP provider as they were cheaper, but my number was still held at the old SIP provider and couldn't be ported. I explained the story and asked if they could 'virtually' add that number to my account so outgoing calls would come from that number. They just switched on the feature to enable me to set the caller id to anything as it was easier for them.
This is also a fun attack. Find a provider that does this. Request to port a target number (a bank or an escort service or whatever). Port will stall for a bit, in the mean time, the service provider activates your number internally, so their own dialers route to their "version" of the number. Now you get all the calls from that provider to that number. Forward them to the actual destination (using an unrelated provi…

Its free up to 100K SMS per month. Can find any pricing detail from Facebook.
Haha, this is the digital version of the Indian phenomenon of 'missed calls', used as 1-bit 0-cost notification mechanism. It's become such a cultural artifact, that big companies are now advertising numbers you can 'missed call' and get a callback from. https://gigaom.com/2011/12/13/indias-missed-call-mobile-ecos...
