Conclusion The IP Phone box advertises: plug, dial and save. It should be plug, work, dial, keep working and maybe you will save. FreeSwitch is free, but it takes a lot of time to make it work. It will be released at the end of the month. Hopefully it will be w/o so many errors. There is plenty of help for VOIP using Unix/Linux, not much help for windows lovers. Using products that are in beta phase, takes a lot of work. 11/11/2018 castroCS525
