Re: VoIP Security
I understand that the "Secure VoIP" license is required for SRTP (media/RTP encryption). But is this license also required to activate just Persistent TLS on the terminals? My understanding is it is not needed for TLS but I need confirmation.
I am currently testing with mixed results.
In system1, as soon as I change the transport protocol for (say) a 6867i Mitel SIP Phone from TCP to Persistent TLS, the terminal restarts as per normal. After the restart, the terminal screen looks normal and as if it is registered. But it actually isn't and the LCD screen changes to "No Service" once you seize Line1 for example. It also cannot be called. This system does not have the Secure VoIP license.
I have system2 encountering the same issue when changing to Persistent TLS. System2 has the Secure VoIP license.
I have system3 with the Secure VoIP license and I can switch the protocol to UDP/TCP<--->Persistent TLS with no issue.
I hope to hear your inputs.
