Cloud PBX, also known as cloud-hosted VoIP, is a great option for modern office phone systems. Extremely cost-effective, it can be used virtually anywhere and requires none of the hardware that traditional office phone systems once required. Best of all, cloud PBX simplifies the troubleshooting process. Where traditional phone repair service once took hours or days, cloud PBX issues are quickly resolved online. And many providers offer 24/7 technical assistance.
Solutions to Common PBX Problems
If you’re having problems with call quality, the service provider is not always at fault. For example, when you place a call to a regular landline or a mobile, the call quality provided by the other party’s phone provider is not usually under the control of your cloud PBX provider. Here are five common VoIP problems that sometimes occur, and some tips for troubleshooting them.
Problem #1: Latency
Latency, which sounds much like an echo, is the delay between one person speaking and the other person hearing what was said. The three most common types of latency are propagation delay, handling delay and queuing, or serialization delay. The solution is to prioritize VoIP traffic through policy-based network management, bandwidth reservation, etc. A good quality router may also solve these latency issues.
Problem #2: Jitter
Jitter is one of the most common VoIP call quality problems and is related to poor quality audio, which seems jumbled. Solve jitter problems by using jitter buffers, which stores arriving voice information packets in their correct order. The result? Clean and concise audio.
Problem #3: Poor Internet Connection
Since most ISPs are designed for web surfing, not PBX office phone systems, you may not have enough bandwidth to handle your VoIP. Typically, 100 kbps in both directions is needed to ensure quality calls. The solution is business class high-speed internet service, which your internet provider most likely offers.
Problem #4: Bad or Inadequate Router
There’s no getting around a bad router, which is one of the most common causes of call quality issues. It usually occurs when businesses use their internet service for both voice and data. This only works if your current router is able to prioritize VoIP traffic. Otherwise, you’ll need to install a specialized VoIP router.
Problem #5: Improperly Configured Internal Network
We saved the easiest for last. If you route both voice and data over the same network, you’ll need to properly configure the network for VoIP traffic; otherwise, you’ll have call quality issues. The fix is a business VoIP capable router that is properly configured.
