Automatic client certificate ("LSC") negotiation #10

Closed schorschii closed 1 year ago

schorschii commented 1 year ago

As described in the README.md, besides SIP, SIPS is also supported but needs manual intervention at this time.

The part which is unclear is how Cisco Jabber exactly negotiates the client certificate (called "LSC" - Locally Significant Certificate) with the server using the CAPF protocol on port 3804.

Any help in reverse engineering this is highly welcome.
