SIP ALG
Number one on our list we have one of the most common yet annoying VoIP-related issues. Within this issue, you will call someone via your VoIP, and you will be able to hear them properly. However, the other party will not be able to hear you at all. Your phone will not register or in some cases, you will see that the phone keeps ringing even after you have picked up the receiver.

SIP or session initiation protocol has a method of inspecting each message then exchanging it via private IP address for every public exchange address. This requires ALG or application layer gateway.

Cable Crossing
Cable crossing is a very common issue where your VoIP phone will be functional, but you will hear no audio. Usually, cable crossing also takes place when the VoIP phone doesn’t establish a network connection.
This usually happens because ports are not connected properly. You need to know how to connect your handset port when the ethernet cable is plugged in LAN.
Solution
Just go through all the ports at the back of the handset. Make sure everything is plugged in properly. Check your ethernet cable and make sure it is plugged into the LAN port at the back of the VoIP phone system.
PoE
This is the most frustrating yet most common issue that most VoIP users face. This is the situation where your phone will be connected but will not receive or detect any power.
One of the major reasons can be the installation issue. Most offices use a POE injector or POE switch. It is a switch that uses an ethernet cable to provide power as well as the internet. However, if you are thinking of using the same phone at home and you do not have a POE injector, you need a separate power supply.
Solution
The best solution is to get a POE switch or POE injector that you will be able to find easily from any VoIP phone provider. Most service provider also offers cables, switches, and injector as spare parts. You can use any store nearby or order it online. You can also connect your VoIP phone with a separate power cable as well.
