 It is always a good option to test the stun server before using it. 3CX provides it’s own stun servers (stun.3cx.com and stun2.3cx.com) but it is very important that if you have a VoIP Provider from VoIP Company XYZ, to use the stun server address provided by VoIP Company XYZ. You can use the 3CX Stun server but probably the stun server of your VoIP telecom company will be closer to you and might have less traffic so the response you get back will be quicker. It is always a good option to test the stun server before using it. 3CX provides it’s own stun servers (stun.3cx.com and stun2.3cx.com) but it is very important that if you have a VoIP Provider from VoIP Company XYZ, to use the stun server address provided by VoIP Company XYZ.

 Since the STUN resolution is the source of many (if not the most…) problems concerning 3CX configuration, disabling it is your primary goal. Unfortunately you cannot do it the easy way because you will be expected to enter your fixed public IP before saving configuration, and if you don't have it (if you are on any kind of ADSL, you probably don't….) you cannot disable STUN !! Since the STUN resolution is the source of many (if not the most…) problems concerning 3CX configuration, disabling it is your primary goal.
