Try checking the solutions to common Voip problems before calling technical support :

1) Choppy Voice

Check your internet bandwidth 

  1. Turn off all other computers connecting to your network.
  2. Test your bandwidth speed.  There are websites that offer this free of charge.
  3. Check your running applications for bandwidth usage.
  4. Test for malware and spyware. There are several free anti-malware software available online.
  5. Configure your router’s QoS to prioritize voice applications.

2) Echo

To resolve VoIP echo issues, try these easy steps:

  1. Cover your phone’s mouthpiece. If the echo lessens, it means that you just need to turn down the volume of your earpiece/speakers.
  2. Move your router away from your computer’s monitor, CPU and power strip.
  3. Disconnect splitters and caller ID devices connected to your router and your phone.
  4. Inspect your system’s wiring. Make sure your cables are dry and not too long.
  5. Replace old equipment.
  6. Use a corded phone, instead of a cordless one.

 

3) Jitter and Jitter Buffer

Jitter refers to the variation in the arrival time of voice packets. To ensure that conversations are understandable, the jitter buffer collects the packets first and then sends them to the receiver at an even pace. Sometimes though, the jitter buffer can be wrongly configured, which can result in dropped packets and low quality voice calls.

 

4) Problems with Bandwidth

VoIP problems that are rooted to insufficient bandwidth allotment can be addressed by reconfiguring your router’s QoS. All modern routers allow access to the QoS, where an administrator can assign priorities to different types of applications.

  1. Decrease impeding equipment between your computer/SIP phone, and network connections. For instance, you should connect directly to your router/switch, instead of accessing the net via Wi-Fi.
  2. Check your equipment and wiring. Damaged ones can cause delays, which you may wrongly attribute as bandwidth-related.
  3. Do a power cycle to see if renewed connections can speed things up for you.
  4. Turn off all other applications, especially those that use up a lot of bandwidth, such as gaming apps.
  5. Set your QoS to allot top priority to Voice Applications. Deprioritize gaming and other similar apps.
