What would be the secure way to enable provisioning of a template to a remote P series phone?
Zero Touch works for registrations with DPMA over UDP but the template doesn’t get loaded through that unless the provisioning port is forwarded to the PBX and that doesn’t feel like a safe solution.
I’ve tried getting a VPN configured on those but the P series seems to have a non-working implementation for VPN connectivity. I’ve had a support case (ID 00966285) about this open for a while now that seems to have gotten abandoned by the assigned engineer.
I was finally able to get VPN working today on the P330 with the latest firmware 4_11_4, however, all EPM assigned BLF keys and Speed Dial keys disappear. Phone Apps don’t appear to work while on VPN either, including Visual Voicemail and Status. Also, I wasn’t able to get VPN working with TLS-SRTP at all and have to use UDP. I know there is no need to use both, but there is something wrong there as it can be done with an S-Series. @lgaetz are you aware of these issues or can anyone else confirm the same please?
