Global Call Forwarding was launched in 2007 with the goal of becoming an exclusive outlet for toll free and local numbers. The parent company, United World Telecom (UWT), was founded in Florida, USA over twenty years ago in 1996 and originally operated as a callback service provider. With a growing customer portfolio and increased demand, UWT transitioned to being a call forwarding service provider over time and created Global Call Forwarding (GCF) in 2007 as a distinctive brand dedicated to providing international toll free and local numbers.
Global Call Forwarding LinphoneI have an account with Global Call Forwarding for over 3 years now and have never had any issues. Customer service is very friendly and audio for calls has always sounded perfect. I route calls from France to UAE, and there are never any problems with delays or latency.
I just purchased a 1-800 number for my business and so far the customer service and call quality has been great. I had some questions so I called in and my account manager cleared everything up. He helped me set up call forwarding and voicemail which only took a few minutes.
I’ve been looking for a reliable provider of virtual numbers for a while... and have used multiple companies. My account manager, Nabill, has worked with me one on one and really knows his material. The prices have been sooo competitive. I would recommend Global Call Forwarding for any business that needs international phone services. Thank you!

Well I can tell you that any SIP program can do this, one that comes to mind is Linphone. But you do need a provider. Almost all providers deal with UDP. You might be able to find one that transmits over tcp but that’ll be a very small list. TCP isn’t reliable for VoIP, for media anyway. At best you’ll find one that encrypts the signaling over TLS, which is TCP. But audio, even if encrypted too, is done over UDP.... Source: over 1 year ago
Does Linphone (https://linphone.org/) not meet that need of cross platform (website claims versions for all major OS'es) and open source (https://gitlab.linphone.org/BC/public/linphone-desktop)? - Source: Hacker News / over 1 year ago
Similarly, you can use any SIP (VoIP) provider (e.g. VOIPo Cloud), and configure the SIP account details in your native phone app. This way you will also be able to use a SIP softphone on your computer (e.g. LinPhone on Linux or Telephone on Mac), or even a real SIP phone in your home. Depending on your SIP plan you may or may not be able to make international calls this way. Source: over 2 years ago
