Has anyone here signed up with Sonetel?
Sonetel is just one of many SIP providers. SIP is a protocol used to make VOIP (Voice Over IP) calls. The SIP protocol and SIP providers existed long before Skype. Skype simply introduced its own proprietary protocol, and became very popular. Now, with Skype's demise, many people are returning to SIP.
The three biggest SIP VOIP providers for residential users offering U.S. phone numbers are
Callcentric.com,
VoIP.ms, and
Anveo.com. In SIP provider terminology, the phone number you use for incoming calls is called a DID number (Direct Inward Dialing number). Since SIP is a protocol, you usually have to assemble the things you need, rather than getting a single all-in-one package like Skype offered.
If you need simple advice, just go with
Callcentric. It has been around for a long time and is known for being reasonably reliable. I've heard good things about their SMS app. The prices aren't the cheapest, but they are reasonable. (Google Voice is free, but I’m guessing you’re unable to get a Google Voice number for some reason.)
To get a phone number from Callcentric, check the
plans on their website. The "Dollar Unlimited" plan gives you a number in certain selected states - likely rural areas. The "Pay Per Minute" plan is better if you want the number to match your preferred U.S. location.
You can add their basic SMS messaging feature on top of your phone number plan. It costs $1/month, plus 1 cent per message.
When you sign up with a SIP provider, you’ll get a SIP address like "
[email protected]". To place calls, you can use a softphone such as
Zoiper (there are many other options). Zoiper has a desktop and mobile clients. Incoming calls to your phone number will ring through the softphone app.
It’s kind of the same story as with email. You can get an email account and address from one provider, but then use Thunderbird on your desktop and a third-party email app on your mobile device. With SIP providers, it’s similar: you get a SIP address, which you can use with different apps or devices, and connect phone numbers, depending on your needs.
