How to increase Quality of VOIP?

Hi There,

I have Road Runner Cable, and Phone Power phone. When i am uploading/downloading something on the internet the quality of our calls is horrible (sometimes not even able to use the phone).What (if anything) would fix this? A higher speed internet connection? Or should we look at switching to a phone line that is not VOIP?


Regards,

The quality of VOIP depends on certain factors.Firstly, use the branded and good quality handset, that has already been accepted in the market by customer feedback.And secondly,the Coder-decoder(called Codec pack),which utilises low bandwidth and more CPU utilisation.And lastly there should be good quality of internet connection.If it is not there, the handset and Codec pack are of no use.

Check your QOS on your router.
Brands like Draytek and AVM Fritz!Box make sure that you can give priority to your phone calls above your other internet Usage...

Hook the phone’s router in front of the computer or your router. That way the phone gets dibs on the bandwidth.
VoIP,email,web browsing, downloading files, videos, music, etc are all competing for the same limited bandwidth space.
Combine all that with the fact that many ISP’s don’t always truly deliver the bandwidth they promise and now that big data pipe becomes a narrow pipe trying to squeeze at that data through at the same time.
1) Buy the fastest service you feel comfortable paying for.
But, I have heard stories where the ISP’s don’t always deliver all that extra bandwidth you are paying for…. so what can your do but give it a shot…
2) Of all the data services, VoIP is a “real-time” data service. It can’t tolerate data bottle-necks like other data sources can. When your data pipe gets squeezed, VoIP suffers the most. VoIP can’t tolerate dropped packets, or even delayed packets like other services can.
Sometimes we just can’t have it all at the same time. Use discretion when you do heavy surfing and downloading. Try to make your VoIP calls during your data lulls rather than on the usage highs.
3) When you have a choice, use lower bandwidth VoIP Codec compression. Lower bandwidth, high compression Codecs are more bandwidth efficient and often provide better efficiency than the high-qualify Codecs.

Buy the fastest service you feel comfortable paying for.

Of course. You are using the same internet connection so both will suffer (data and voice)

I suggest either stop your upload or download while talking (browsing is okay) or set up your QOS so it will give priority to "voice" and your download and upload will crawl while you are on the phone.

I am totally agree with what you said as, it is actually required but, there is some other thing which is also important to know that there are some VOIP business phones provided by some companies which you can use.

Thanks

Your router and internet connection should be very good if you want to increase quality of your voip.

In most case it is the Internet connection that is to be blamed, but there are some other factors too that affect the voice quality, like the handset, and the router. Now, let me ask you if you have the equipments from your service provider or you purchased it on your own. If you purchased it on your own then the compatibility of the equipments is causing the problem while if it is the other way around then just call the service providers customer care get them to check it for you. Hope that it helps.

Check your internet connection and see if it's okay for VoIP. VoIP Test - Is Your Connection Fast Enough? | Tools | Bandwidth.com

Latency should be around 200ms, higher than that might result in echoes or delays.

there is one way out which i have tried and it works if you want to stick to your current services.

Just switch off the entire system for 5 mins after every 2 or 3 hours and it will work for you for sure.

Alick based on my experience, if you are not watching videos on Youtube or similar sites and not downloading files, you can still browse the internet and talk using VoIP without affecting its quality...as long as you have at least 1mb connection.

Again i will recommend you to switch your ISP and connect to high internet service provider then u can enjoy voip service.
