If you've yet to launch even a VoIP (voice over IP) pilot, you might feel like the classic lonely guy knocking around his empty apartment while a wild bash rages one flight up. Only instead of missing out on loud music, iffy shrimp cocktail and a screaming morning-after headache, your company is doing without productivity enhancers such as GUI-based soft phones that can integrate with desk phones and address books. The same application may also communicate presence information about the availability of others on the system. In addition, a number of IP PBXs have a "find me, follow me" feature that lets you contact a cell phone if, for example, the office phone doesn't answer. Some will ring an office phone and a cell phone at the same time. Moreover, it's a buyer's market for VoIP systems, Gartner reports that at year-end 2004, sates of new IP-PBX systems surpassed those of conventional PBXs, and that by 2010, IP-telephony products will represent 90 percent of new system sales.
