Important: To be able to use TLS, TLS communication port has to be enabled on the phone system and set to 5061. You can find the menu below in MXAdmin Provision -> SIP and RTP, SIP settings tab. If you change settings in this window system will have to be rebooted to apply settings.

2. Registrar port 5061

If TLS does not work, try TCP

Legacy – use alternative UDP SIP ports

On Zultys phone systems  configured by Vatacom there is an alternative UDP SIP port  6060 .
