The best thing about this softphone is its user interface which has been very easy for me to use as I am new at using telephony software. It does not work with my computer or laptop so it makes things difficult when trying to call from home. This product isn't good in any way but rather just bad because of the problems i have had while attempting to make calls from home. Its also very expensive compared to other similar products out there. I would recommend switching to another phone line service provider if you are looking for great quality telephone lines then go ahead and switch over and try mi collab first. As i said before, I was having issues with making cell phones calls from home but once switched to mi collab everything worked perfectly! No more dropping calls, no more voice quality loss and being able to pick up those missed calls right away!
