Before setting up up your Voip you have to test if your Lan can handle the addition packets, Bandwidth and hardware necessary to support Voip. Remove unecessary routers, switches and hrdware between where the voip call originates and where it finally hits the PSTN. Isolate the Voip traffic from your existing data network as much as possible via a virtual lan. Give the Voip Packets their own section of bandwidth. Add prioritization to your routers and firewalls to ensure the voice traffic recieves the best treatment.

10)
– Making calls via voip, including internation calls, are cheaper than normal PSTN calls, that means less costs for a business and more profit
-Voip is easier to install and use. potential problems are most of the time easier and faster to to solve than land lines
-Voip calls only need internet so that means you can makes phones anywhere in the world and this is great for business when travelling
-Voip also allows for video-conferences and share files and documents. Can transfer video audio and and other documents
-Better scalability as new componets can easily be added if you want to increase productivity

11)
– latency is only a problem when your average network latency it is more than 150 milliseconds
– Jitter is the th extra boost in that pushes the normal latency to level in your lan to a point where it starts to dropping packets
– Packet loss that can be caused by many problems
-interference and buzzing is usually associated with the introduction of a signal or voltage into the VoIP connection that is then converted into an annoying sound
– Poor internet connetion
– Inaderquate router

12)
– latency is only a problem when your average network latency it is more than 150 milliseconds
– Jitter is the th extra boost in that pushes the normal latency to level in your lan to a point where it starts to dropping packets
– echo can affect sound quility and is caused by the far-end point
-sound interference

-G.711 has a propagation delay of 0.75 ms and a bit rate of 64Kbps and a mos score of 4.1
-G.723.1 has a propagation delay of 30 ms and a bit rate of 6.3Kbps and a mos score of 3.9
-G.726 has a propagation delay of 1 ms and a bit rate of 32Kbps and a mos score of 3.85
-G.728 has a propagation delay of 3-5 ms and a bit rate of 16Kbps and a mos score of 3.61
-G.729 has a propagation delay of 10 ms and a bit rate of 8Kbps and a mos score of 3.92
When choosing a codec it is important to look at the compression ratio, call quality and propagation delay

14)
An echo effect is typically due to a blockage or mismatch, which results in the signals bouncing back from where they came.
-Hardware Interference can be due to a number of reasons such as poor quality splitters, poor or damaged wiring, long runs of mangled telephone cabling, or even shoddy analog headphones,
-Feedback occurs from the far end telephone, and usually results in the voice traveling back to the mouthpiece from the earpiece through the receiver itself
-Intensity and volume, the intensity of the echo wave determines how noticeable the echo will be, the volume of the phone itself can sometimes have an impact on echo
-Electro magnetic interference can occur when one positions their systems too close to other electronic devices

15)
-A VPN connection supports strict security by helping manage multi-office locations, securely connecting remote workers, encrypting your connections.
-Establishing call routes allows your provider to set up a profile where only you as the customer can send outbound traffic to those desired routes.
-Access lists helps the provider to lock down a customer’s account to prevent identity theft or scamming.
-The intrusion prevention measures inspect traffic packets to prevent and stop system penetration to protect customer information and customer billing.
-Credit limits based on both current and historical spending allow the VoIP provider to limit any abuse or misuse not caught by behavior monitoring or intrusion prevention systems.
