We currently have a Mitel SRX5000 running MiVoice Office 250 Release v/ 6.1 sp1 call processing v/ 6.1.4.64

Currently It is sending voicemail to email using TLS 1.0. Does the version we have even support 1.2? and if it does, where would we go to enable it since it us not an option under email gateway…

The last I asked about this, it wasn’t available yet, although I haven’t asked in a while. Have you asked your vendor?

Looks like 6.2 SP2 does support TLS 1.2, but not the version you are currently on.

The latest 6.3 SP7 fixes all the email gateway issues.
