Voice over IP Phone Service

Specializing in multi-site voice & data connectivity,

 

Bring your remote offices closer together by joining multiple locations, whether across town or across the country, into what effectively is one big company-wide unified communications system. A multi-site installation consists of two or more distributed systems that are loosely coupled. Each site is its own distributed system and has one or more logical connections to other sites over one or more physical connections.

Connect up to 100 offices across your WAN or over the Internet without dedicated lines or long-distance toll charges. Streamline the way your business communicates, utilizing a multi-site unified communication system tailored to meet your business needs.

 

 

One challenge businesses face when implementing a Voice over Internet Protocol (VoIP) system is how to allot enough bandwidth for voice traffic. The task of managing traffic becomes even more complex when businesses have Internet connections at more than one location.

 

Unifying communications systems at multiple sites can save businesses money on operational costs and phone bills. Internet connections supporting VoIP systems must therefore offer a consistent level of available bandwidth to ensure high-quality audio. To enable VoIP communications between multiple sites and establish a smoothly functioning phone system, businesses must understand each site’s unique bandwidth requirements.

 

QoS refers to how data packets transmitted over IP networks are “tagged” to establish different priority classes for the transmission of different types of network traffic. QoS is enforced by VoIP hardware (e.g., a router).

QoS settings can be configured by administrators using the software interfaces for these devices. In some cases, however, network engineering may be necessary when businesses need to increase the overall level of bandwidth to adequately establish QoS. Network monitoring software on the sides of both the service provider and the customer can help to determine whether QoS mechanisms are operating effectively.

 

Generally, voice packets are assigned the highest priority class to ensure that voice applications continue to perform smoothly in sub-optimal network conditions. Web-based applications that are less sensitive to network problems are assigned a lower class of priority. Ironically, this can mean that Web-based applications function less smoothly than voice applications in certain network environments (as evidenced in the above chart).

Though QoS engineering and hosted solutions can fix many of the problems facing voice networks, employers still need to vigilantly manage their networks.

 

While personal Web surfing (reported by 46 percent of our sample) may be a waste of employee time, it’s not as much of a threat to voice traffic as activities involving streaming media.

Streaming demands much more bandwidth than Web browsing or downloading, since packets have to arrive in a timely fashion to ensure high-quality audio and video.

 

What is centralized call processing?

Centralized call processing for a multisite telephony deployment means the call processing intelligence (i.e., the IP PBX) is provided at one central site and all telephony endpoints, whether physically located at the same site or at a remote site, register to this central IP PBX. VoIP technology makes this setup possible.

 

 

Should there be a centralized PSTN connection?

A centralized architecture can vastly simplify PSTN connectivity. It grants the ability to connect all corporate branches and headquarters to the PSTN via a single connection at the central office (HQ). This way, dial plans can be easily normalized, costs are consolidated to a single telephone bill, and supplementary PSTN connectivity (with the required hardware for it) is unnecessary at each individual branch.
