When you add team members to LinkedPhone, a company directory is automatically created for you. There is no need to build or maintain a company directory manually as team members enter and exit your business. Callers may search for team members by name or extension.
On top of that, Nextiva instant messaging lets you tend to clients who are not big on talking but still want to get in touch with your company. And with its top-of-the-line cloud PBX, you can kiss your traditional desk phone goodbye. Small business owners can take advantage of Nextiva softphones for both internal and external communication over the internet with HD call quality. Larger businesses set in their ways can keep their existing hardware or buy additional phones sold by this VoIP service provider.

In addition to making sure your internet service can handle your VoIP traffic, you also need to make sure your local area network (LAN) can handle it. What makes network management tricky with VoIP is that if you simply drop it onto your network, that traffic will get processed the same as any other traffic, meaning your shared accounting application or those 20 gigabytes worth of files your assistant just moved to the cloud.
But it can also handle other functions, including session setup (initiating a call at the target endpoint—the phone you're calling), presence management (giving an indicator of whether a user is "available," "away," etc.), location management (target registration), call monitoring, and more. Despite all that capability, SIP is simple compared to other VoIP protocols primarily because it's text-based and built on an easy request/response model that's similar in many ways to both HTTP and SMTP. Yet, it's still capable of handling the most complex operations performed by business-grade PBXes.
