[Freeswitch-users] Separate CA authorities for SIP TLS

Hello, I am about to setup TLS SIP interconnect between Cisco servers (C3945) and Freeswitch. CA server for Cisco devices is already in place (located on different cisco server). I want to proceed with CA Root certificate generation on Freeswitch server as well. My question is if i could use different CA authorities (separate for Cisco devices and the one for FS) for SIP TLS calls coming back and forth between Cisco and FS? Thanks Maciej.
