How can I call cell phone from computer for free?

All right, it is possible, but may be somewhat mechanical toachieve. There are various ways to achieve this. But, I will only offer onethat is almost certainly the simplest solution, but will still require someexpenditure and technical ability. My solutionis completely based on the landline not on cell phone I hope it might be ofyour help. This ATA has 2 ports built-in, one port connects to PSTN telephoneline. The other Port connects to your telephone. The ATA allows you toconfigure it to connect to BYOD VoIP services. So, if your VoIP serviceprovider allows BYOD, this device can work for you. It can be configured, byyou, to accept calls on the PSTN landline and ahead those calls through yourVoIP carrier that it is give to through.
