What the Experts are saying!
“There is no one architecture (yet) that can be called the standard for a network phone system. The important thing is to follow a strategy that makes sense for your business.Trashing your PBX and going all IP immediately probably isn’t it.”
Bill Michael - Computer Telephony
What the Experts are saying!
“The underlying assumption regarding ToIP is that the LAN/WAN is always available, with minimal downtime. This is a very risky assumption, because no LAN/WAN infrastructure is currently designed to meet the 99.999% reliability level of a PBX system.”
