    I am running a commercial version of 3CX v.9sp1 with a few external extensions (all CISCO SPA-502 phones) working all fine.
    However; I need to secure communication between those external ext. and 3CX, and for various reasons, I do not want to use VPN setup.

    Would you please help with suggestions on how to setup SRTP between 3CX and SPA-502 phones?
    I can not find anything in the documentation or Google.

    In SPA-502 web interface there is a field for SRTP Key, but I do not know where to set this in 3CX and what else needs to be set-up in 3CX for this feature to work.

    Thanks in advance.
