Best Way of Receiving Calls Without SIM (VOIP)

[county93]

Does anyone know how I make an outgoing call to an actual number in these things as opposed to another SIP account? In Linphone, I tried to connect to a number, such as 123456789, and it connects to 123456789.linphone.org.

Is there a specific item I need to put in to get it to dial (like "dial:123456789" or "phone:123456789" or call 123456789" so it tries to call a normal phone line as opposed to a SIP address?

You need a SIP provider that allows you to access the regular phone system. Unless something has changed recently, Linphone by default does not connect to the regular phone system. It can, but you must contract with a SIP provider and input their sip URL. Then you can make and receive phone calls. Search google to find sip providers in your region.

JMP.Chat will make outside calls using VoIP. I'm doing that now. You have to set up the phone number first in a contact in an XMPP Client like Gajim or a client that may work with your OS. You can call using wifi, too. I can call landlines or other mobile phones. JMP.Chat works on the XMPP system and uses OMEMO encryption. The people at JMP.Chat are working on making a dialing app to make things easier. I paid 5 months in advance and each month is $2.95 USD a month for 120 minutes of call out time each month. I seldom use that much time with dial up calls because I use the free chat options like alot of other people. Gajim and other XMPP clients have the free chat option like those of Telegram or Signal. XMPP the way I am using it is probably more secure. JMP.Chat works like any VoIP service and I can get SMS messages from banks, eBay, etc. It's all working for me as a regular dial up call service.

It will also do voicemail and voicemail transcription to text. You can set up the call greeting yourself also by recording online or sending in a .wav file. I sent the .wav file in and used a Sprint/AT&T like voice greeting for voicemail to record that .wav file. I found an online service that I was comfortable with that made the text to speech recording. JMP.Chat is working to make the service easier, too.
