I have no issue with VoIP. I use it all the time. I also know that the quality of a VoIP call varies from time to time when I am working remotely, especially when I am travelling. The hit and miss of VoIP, and the uncertainity of the call quality makes it very difficult to count on, which is why, when I am on the road I use the Avaya IP Office One X Portal. Not only does the software work on my MAC, but, the Telecommuter Mode allows me to use my landline (home phone), desktop on my MAC, and take control of my cell phone or home phone as if I am in the office. If I need to make a call I use One X Portal, type the number in, and my cell phone goes off hook and immediately makes the call. Every customer I show this to is blown away.
I wrote a post last year titled “The Office Phone is Dead“, One X Portal is the reason I believe the office phone set, NOT phone system, but phone, is dead.
