Just checking to see if anyone could tell me what phone system they are using with Zoho that is on the list of systems that integrate with Zoho.  I use Vonage and have been with them for quite a few years but their service has really gone down hill and they are almost impossible to get a hold of when an issue comes up and then when you do get a hold of them you get the run around.  So frustrating!  It never used to be like that with them and I see a lot of reviews lately where current or previous customers would not recommend them to others.  I am also at that point as well but I don't want to go from one problem company to another.  Would anyone be willing to share what phone company you use and if you would recommend them to others?

What you like and don't like about them?
