Is it really that router model 1841 resolve the voice quality issue when using the Internet?
I heared that using the router model 1841, if the users are doing download & upload and they are using the bandwidth full, then once the IP Phone is going to be used, an enough (let us say a dedicated bandwidth, or a priority) will be given for the IP Phone to guarantee that voice quality will be fine and the data (download or upload) traffic will not causing a cutting in the voice.
Is that really possible?
If yes, what about 800 series routers? They can do such thing?
Really I am so interesting in the Quality of Service and Priority because of the voice, this is very important for voice application.
Any help and advise?
