Forrepparttar 147332 network administrators, a VOIP phone system means they only have one network to maintain instead of two. The portability ofrepparttar 147333 phone system is also greatly simplified.

The MAC (move, add, change) process is made much easier, and you will not have to call your system/service provider for every MAC you carry out. All this means lower ongoing costs for your company.
