Business VoIP has come very far. From being a support technology, it has been adopted as businesses’ main means of communication. It is a robust and reliable telecommunications system that is still on the rise. Already at par (and even better sometimes) to wireline and mobile communications, it continues to improve. It tags along unified communications in taking business telecommunications by storm.
Now, is it perfect? Of course not. The technology still experiences some technical glitches. Most of these minor issues can be fixed by your IT guy.
No Dial Tone
This mostly occurs at the beginning of your setup. You may have gotten your VoIP service provider to also fix your system. One of the things they need to do is to provision your phones. They should also set up your router port forwarding correctly.
So, if you experience zero dial tone, check out how your phones are provisioned and how forwarding is set up. It should have been set to auto-provision. If not, you may need to do it manually. This is also true for the additional phones that you might need to add later on.
Regarding forwarding, make sure that your setup forwards to ports 5060-5090 and 16384-16482.This is also what you need to do if you have a dial tone but no audio. The forwarding of voice packets is not correct. It should forward to ports 16384-16482.
Problem with echo date back to when the phone was invented. It does not solely happen with phones set up for VoIP.
With echo, the common cause is your speakers being too close to the microphone. The microphone picks up the sound and echoes it. A simple solution is to lower the volume of your speakers. If there is still an echo problem, there might be something wrong with your phone unit. You then need to have it serviced or replaced.
This is one technical issue that might have deeper roots… deep, as in it could be your broadband service. VoIP requires good internet connection, at the very least. You should have ample bandwidth allotment to support the requirements of digital telecommunications. To help you monitor your service’s performance, sign up for VoIP Spear. Through persistent testing, you can monitor for packet loss, internet speed, jitter and MOS score 24/7/365.
Choppy audio may be the result of problematic internet connections or bandwidth allotment. The best solution then is to upgrade your service.
But, as a temporary solution, you can tweak your QoS, codecs and jitter buffer settings. Your QoS should prioritize video and voice applications. Applications that eat up a lot of bandwidth should be put at the back of the line. For your codecs, G.729 is best when you don’t have that much bandwidth allotment to work with. Likewise, you should increase the depth of your jitter buffer.
Other Technical Problems
The problems listed above are basic frustrations that may be felt once in a blue moon.
However, if you get one or more of these intermittently, you need to look at your VoIP and internet service providers. You might need to reassess the service that you’ve bought, and switch providers.
