Which sip ports do you advise to use if 5060 port is shown closed by provider?
What do you mean by
Your VoIP provider will tell you which port to "contact" them on, and in some cases it may not be 5060, but they will specify.
If you mean that your ISP is blocking your use of 5060, or is already making use of it within your modem/router device, then just start moving up until you fine a value not used. 5061, 5062, 5063.....
I tested port scanner and saw that 5060 port has been closed by ISP and it gives an error in 3CX firewall checker. But there are not problems with voip calls. Does other ports give the same call quality as 5060 port do?
It is nothing to do with call quality. That port is only used for messaging, call set-up and tear-down, progress information and the like. Voice traffic uses other ports. Think of it as a house address, if you want to get your mail then the post office has to use the correct address, whatever that may be. As long as the port you choose is not being used by another application, it should work for you. For extension devices that will be used at hotspots (locations that I have no control over), I quite often assign a port in the 507x range to avoid possible conflicts.
When you register with a provider you specify which port to reach you at.
Which option is right?
1. Sip port: 5062, SecureSIP: 5061, Tunnel port: 5090
2. Sip port: 5070, SecureSIP: 5061, Tunnel port: 5090
3. Sip port: 6060, SecureSIP: 6061, Tunnel port: 6090
SIP Port, TCP/UDP, 5060,6060,7060,8060,9060
Secure SIP Port, TCP, 5061, 6061, 7061, 8061, 9061
Tunnel Port, TCP/UDP, 5090, 6090,7090,8090,9090
There is no right or wrong, as long as both ends are set to use the same port, for each service. Some functions are easier to change, some probably don't require changing from the default. In cases where 5060, and perhaps 5061 is being reserved by your ISP for local phone services, then you may be forced to change it/them. The tunnel port, 5090, isn't commonly used by other VoIP providers and probably wouldn't require changing.
Thank you very much.
