Are there any providers? In the UK?
Does 3CX even support SIP over TLS for Trunks?
Wow, this is surprisingly unpopular.
I don't think 3CX does support Secure SIP for trunks (still not sure). Does anyone know if 3CX support SIP over TCP for trunks for any providers?
What about SRTP for trunks? At least the voice would then be encrypted even if the meta data is in the clear.
I'm surprised what with SSL become the default for web browsing there is so little interest in encrypting voice trunks.
Anyone any ideas why?
Ahh, there is an SRTP tick box on the trunk options screen in 15.5.
