I'm trying to setup encryption between a CUPC working as a softphone and CUPS/CUCM. The customer requirement is to encrypt the signaling and media traffic. The CUPC works perfectly without encryption. But if I set the SIP Security Profile to encrypted, I can not register the CSF. The same for the deskphone control. If I put the user in the Secure CTI group the Deskphone control stops working.
Does the CSF support encrypted SIP connections and SRTP? How do I import the certifactes in CSF? I did not find a deployment guide for this scenario. Does anyone setup this before and point me to some documents.
