Setting NAT settings is vital when using VoIP. Without proper NAT settings, VoIP calls will suffer. The amount of latency can vary from one person to another, and it is subjective to the individual. Another thing to consider is jitter. If the latency of your VoIP call is too high, it may be too slow for your other services, including video streaming. Luckily, there are ways to minimize these issues.
The first step in solving these issues is to check the NAT settings on your VoIP device. This is essential because NAT settings can block SIP packets from reaching their intended destination. To solve this problem, make sure the underlying PBX of your service provider supports SIP. For example, a Yealink phone will display a Rport setting when the SIP header is enabled. You can also change the UDP timeout, which should be set to 300 seconds.
Next, check if the VoIP device is too far down the network chain. Do not connect multiple VoIP devices to one router, since multiple routers have to maintain routing tables and data packet routing tables. This could cause double NAT. Alternatively, check if your VoIP device is connected to more than one router. A dual-NAT situation could cause data packets to be lost altogether. To avoid such a situation, you can change the NAT settings of the other routers in the network.
While money can solve some problems, it doesn't solve all of them. You may have high latency, jitters, or a lack of bandwidth. If your VoIP solution can't handle these problems, you may want to consider a faster internet package. But before you make any changes, make sure you review your network and VOIP solution thoroughly. Make sure everything is working properly. Make sure that nothing interferes with your VoIP calls.
