If the provider cannot give you this information either log in to your ATA and find out and if this is not an option, assume both for the purpose of configuring your settings. You need to know this when configuring certain settings. Usually this will be either Transmission Control Protocol (TCP) or User Datagram Protocol (UDP). Protocol for SIP (Session Initiation Protocol).The important parameters to know are as follows, and tend to be readily available on a provider's website (or should be!): Provider Settingsīefore you can optimize any settings for VoIP in your router, you first need to know some details about the traffic your VoIP provider is sending to you. #Voipraider sip settings softwareOne final note here, it is also worth checking that your router has the latest software image installed on it. This is often referred to as "double NAT". The reason is that each additional level of NAT is another potential failure point for your calls as each has to keep routing tables for where to send data packets. In other words, do not connect them to a router which then connects to another one and then to your Internet modem. If you have multiple routers in your network, and note that this does not include switches, avoid having your VoIP devices too far down the chain. Very few devices use WiFi at this time of writing so for the purpose of this article, our focus will be on hard wired connections. Your analog phone then connects to the ATA using a standard phone cable.īusinesses tend to use IP phones, again hard-wired using CAT5/6 Ethernet cable to your router, often via a switch. If you are at home you likely are using an Analog Telephone Adapter (ATA) which connects to your router using hard-wired Ethernet cables. Device Placement in NetworkĪssuming the tests pass and you order a VoIP service, it is important to touch on the subject of placement for each device in your home or business network. If your underlying Internet connection is poor, for example a satellite Internet connection, optimizing router settings will have little impact on improving your overall call quality. VoIP Testīefore you even order a new VoIP service, run a VoIP test to get a feel for how good your Internet connection is. There are a number of items to consider during the setup phase of your phone system. Setupīefore jumping into settings, we should first touch on the overall setup. Routers used for VoIP typically cost less than $200 for home users and small businesses but can reach thousands of dollars for high end enterprise functionality. It is important that we conserve WAN side IP addresses (for IPv4) as there is a shortage of them so NAT really helps in this respect. In other words, LAN side networks can be common address ranges used by all of us and NAT maps this to a dedicated IP address specific to your connection to the Internet. One further benefit is Network Address Translation (NAT), which re-maps IP addresses from your private network (on the LAN side) to the Internet (WAN side) thus conserving the number of IP addresses that each home or business requires. It also frequently acts as a firewall, ensuring that your Local Area Network (LAN) is not exposed to the outside world without your approval. A router is a digital device that routes data packets from one network to another, by intelligently examining the source and destination addresses associated with each packet.
