I work with a small business that will be doubling in the next few months and doubling again in about 6 months. We are looking for a phone system that meet our needs. We all have laptops because we are on the go so I don't know if a phone system that works with the CPU will really work for us. Right now we are only 4(locally) and need individual voicemail. I don't know very much about phone systems but I have been learning. We were looking at the NEC Aspire S KSU. I was wondering if anyone would recommend this phone for us or any other phone system??
