Top 7 Common Causes of VoIP Voice Quality Problems
Wednesday, July 7th, 2010Top Questions and Answers about Hosted VoIP/Hosted PBX Service
Wednesday, June 30th, 2010Q:Â What is Hosted VoIP/Hosted PBX service?
A: Hosted VoIP/Hosted PBX service provides advanced telephone system features as a service over the Internet. Many advanced features are uneconomical to include as part of a traditional telephone system. Hosted service providers host the costly central equipment of the telephone system on their premise and use the same equipment for many of their customers.

The Top Mistakes Made When Selecting a Hosted VoIP Provider
Wednesday, May 26th, 2010More and more companies are throwing out their tired old telephone system and replacing them with state-of-the-art Hosted VoIP or Hosted PBX services. In addition to lower telephone bills and getting away from 1960s phone line technology, the benefits are wide and far ranging. They include virtual local numbers, telecommuting, connecting multiple locations together through voice, Personal Telephone Numbers, Mobile PBX, Private Faxes, Unified Communications and many more.
Regardless of their reasons for choosing a Hosted PBX or Hosted VoIP provider and the goals that accompanied the decision, not all deployments of Hosted PBX services are successful. Here is a list of the top mistakes made when choosing a Hosted VoIP service and how to avoid them:
1. Selecting a provider that is new to the industry. Providers that are new to the industry may not know how to successfully deploy their service. In addition, they will be learning and solving new problems while using their customers as Guinea Pigs. Worse, they could go out of business with little or no notice which could have devastating effects on their customers.
Choose a provider that has been delivering Hosted PBX services for a minimum of 5 years. The length of time that a provider has been in business is an indicator of quality service, satisfied customers and financial health.
2. Deploying a Hosted VoIP service with an Internet connection that is not ready for VoIP. Approximately 60% of all headaches related to VoIP are usually the customer’s Internet connection. An unstable or insufficient Internet connection can cause choppy and garbled voice, dropped calls and a frustrated staff.
Make sure that your Internet connection is large enough, stable and clean of problems before Hosted VoIP service is installed. The Hosted VoIP provider should have tools in place to help determine stability and diagnose issues. Ask them to explain how they are going to do it. If their explanation is not understandable, then they probably do not understand it either. Remember, the Internet pipe has to be stable and large enough to handle the number of anticipated simultaneous calls.
3. Not understanding the calling plans and hidden charges before selecting a service provider. The cheap pricing advertised on websites can be very appealing. In some cases, all is not what it seems. Unlimited calling plans frequently only include the provider’s network which are usually very small. Off network usage can be as high as $.065/minute! The average desk phone is used approximately 750 minutes/month adding anywhere from $20-$50/month per user. Not cheap!
Find a hosted VoIP provider who offers an unlimited plan for placing local and domestic long distance calls. The variable plans are too unpredictable in price and rarely a good deal for their customers. If you do select a variable plan, make sure you know the per minute charges. Estimate your monthly usage and do the math. If you are not sure, use 750 minutes per month per phone.
4. Selecting a provider that does not deliver crucial features. Hosted PBX providers offer many exciting new features and capabilities. However, some of your most common phone system functions such as paging or Busy Lamp Field (who is on the phone) may not be offered at all.
Do not take the basic features of your telephone system for granted. Spend some time watching how the system is used and which features are instrumental to the smooth operation of the company. Verifying that the Hosted VoIP provider furnishes these features will save some nasty surprises later.
5. Electing a provider that does not assist in prioritizing voice traffic as it goes out on your Internet connection. Internet connections from cable companies and DSL circuits have lower upload speeds to the Internet. Unprioritized voice and data traffic compete for this limited resource. Sending a large e-mail while conducting a phone call can create choppy voice and even dropped calls.
Find a VoIP provider who will assist in prioritizing traffic. Ask the potential provider how your data vendor can prioritize their voice traffic. If they cannot give you an answer or they claim it does not need to be done, find someone else.
6. Making a change of providers without learning service termination and other charges that may apply.
Vendors offer attractive pricing and reduced installation charges in exchange for long term commitments. Review your contract and know any remaining term, cancellation procedures and termination charges. Do not get surprised by these charges after you have already committed to another provider.
Hosted VoIP services deliver the ability to reduce phone bills, lower overhead and transform the manner in which a business operates. Avoiding common mistakes in selecting a provider increases the likelihood of a successful installation allowing the business to take full advantage of the powerful capabilities that these services supply.
Wireless Enabled ISP Routers Will Cause Problems with Hosted VoIP Services
Tuesday, March 9th, 2010Many major Internet Service Providers (ISP) such as Charter, Comcast, AT&T and CenturyLink Telephone will install wireless enabled Internet routers as an added benefit to their customers. In some cases, these wireless enabled routers can cause voice quality issues with your VoIP, Hosted VoIP, Hosted PBX Services and/or network interruptions.
Most WiFi enabled access points operate in the 2.4 Ghz frequency range. This unlicensed frequency range is also shared by many common household and business devices such as cordless telephones and microwave ovens. Use of these devices within range of your wireless enabled ISP router can cause interference and other negative effects ranging from seemingly insignificant brief Internet outages up to the need for router resets. Internet outages lasting only several milliseconds will be disruptive to VoIP calls using a Hosted PBX or Hosted VoIP provider.
If your ISP router is equipped for wireless networking service and is not being used on your network, I recommend the wireless feature be turned off. Turning the wireless feature off eliminates the negative effects of any interference and a potential security risk to your network.
If your ISP router is equipped for wireless networking service and is in use on your network, it could be a source of negative voice quality issues as it bypasses the necessary quality of service (QOS) management for voice traffic. Migrating wireless network devices to a separate wireless access controller is recommended. Further, when you use a separate wireless access controller from your ISP router, interference from other devices in the same frequency range will have no effect on the operation of your Internet router.

Will Your Internet Connection Destroy Your VoIP Service
Wednesday, March 3rd, 2010
If you are thinking about deploying VoIP (Voice over Internet Protocol) communication in a Hosted VoIP or Hosted PBX system and its many benefits for your business, you need to examine your Internet connection as it can be the source of many problems. Although you may be satisfied with the performance of your Internet connection for data purposes, it may not be adequate for Hosted VoIP service.
VoIP communication is very sensitive to network problems. In VoIP, the voice signal is converted into a stream of 1s and 0s. The stream of 1s and 0s are then grouped into individual packets similar to data packets. The packets are sent to the receiving end accompanied with the appropriate header (IP Address of the receiving end, prioritization flags and sequence information).
Packets travel the Internet frequently in different routes and will not be received in the correct order, if at all. Problems can occur at the receiving end where the packets must be reassembled in the appropriate sequence and in time to have the 1s and 0s converted back to voice to be heard without disrupting the natural flow of the conversation. Data packets are not time sensitive. Small glitches in your Internet connection may be perceived as slow Internet on your computer, if noticed at all. With VoIP, small glitches can cause choppy voice or more severe problems including dropped calls.
The majority of issues that cause voice packets to be lost or received too far out of sequence for quality voice playback happen on your side. These issues include insufficient Internet speed, poor Internet Service Provider (ISP) service, an unreliable Internet circuit into your building, wiring inside your building and outbound voice packet prioritization. It is not enough to simply have a broadband connection. You need a high grade broadband connection to deliver the call quality you require to run your business.
Most ISPs run on a business model of oversubscription. High demand on these ISPs results in jitter and latency. In addition, quality Internet providers do not always install the best circuit possible. In many cases, the circuit that connects you to the Internet is deficient. For example, you or one of your neighbors may be using a commonly deployed T1 circuit. If your carrier has placed a T1 and your Internet DSL in their same cable bundle, the T1 will interfere with the frequency of the DSL and will make good voice quality impossible.
Bottom line, for successful Hosted VoIP or Hosted PBX deployment in your business, you should make sure that you are using the right ISP for your area, you have sufficient Internet speed and you have a reliable circuit. Further, voice packet prioritization need to be properly set.

Four Steps to Determine Whether Your Internet Connection is Ready for VoIP
Wednesday, March 3rd, 2010If you are thinking of deploying a Hosted VoIP or Hosted PBX system for your business, performing the following steps will help determine if your Internet service is adequate.
1. Ask your VoIP service provider whether they have experience with customers in your area using your ISP. Good service providers will be able to tell whether their customers are getting good results with certain ISPs.
2. Do not take your ISPs word for the speed they are delivering. In most cases, it will be less. Connect a PC as close as possible to your ISPs modem or router and go to http://myspeed.visualware.com/index.html to run a speed test. Write down your upload speed and your download speed. The lowest speed is the most important which usually is your upload speed.
3. Determine your desired number of concurrent voice calls. Take 75% of your lowest speed (upload or download) and divide by 35Kbps (typical size of a voice call using G.729 codec which most VoIP service providers use). If the result is greater than the number of concurrent calls then your speed is sufficient. Don’t forget that if your speed is measured in Mbps that 1 Mbps = 1,000 Kbps (0.1 Mbps = 100 kbps).
4. Test the quality of your Internet connection using the HostMyCalls ISP Packet Loss and Delay Test Tool. It is free to use and will take less than 30 seconds of your time to start monitoring your IP address. The HostMyCalls Test Tool specifically checks the Internet connection for packet loss and latency (delay). If excessive packet loss or delay is found, it will report whether these are happening at your location or within the network of the ISP.
If you learn that you have a quality ISP, you have sufficient speed to support the number of concurrent calls that you need and you have a reliable circuit, then your Internet connection is ready for Hosted VoIP.
Although a quality connection to the Internet is required, it is not the only thing you should think about when deploying a Hosted VoIP or Hosted PBX system for your business.
