Cisco 8851 VPN

[LSA4]

Hi

I have a ISR4321-v router in the office working as my PBX all the 8851's in the office work fine.

Now i have another 8851 phone at home connected to my home lab, i would like to know is there a way to connect my 8851 at home to the CME at the office, i have client VPN setup(Meraki) for my laptop and it work 100%

I Hope the above makes sense, looking forward to hearing from you

Hi,

In Communications Manager Express 8.6 and later versions, Cisco Unified SCCP IP phones such as 7945, 7965, and 7975 located outside of the corporate network are able to register to Cisco Unified CME through an SSL VPN connection. I do not see any reference of Cisco 8800 Phones with CME through SSL VPN connection.

For  remote phones, you can go through the "Remote Teleworker Phones" section in below guide:
