I have setup an UCM / CMS based infrastructure, but I am not able to use srtp between a CMS room and a Jabber client. The TLS signaling is building up with no problem, only the SRTP does not work. The following error message I see all the time: tearing down unencrypted call 'ef4d4ac9-2767-48cf-8f8c-3dd91045fd9e' because encryption is required call 131: ending; local teardown, encryption required - connected for 0:00
Here you can see what I configured: CUCM setup: - Certificates Internal PKI cert assigned to tomcat, callmanager, ipsec - Secure SIP Security Profile Device Security Mode: Encrypted Incoming Transport Type: TLS Outgoing Transport Type: TLS X.509 Subject Name: cms.domain.local Accept Replaces Header - SIP trunk SRTP Allowed Secure SIP Security Profile Standard SIP Profile For TelePresence Conferencing Normalization Script: cisco-meeting-server-interop CMS setup - Certificates Internal PKI cert assigned to webadmin, xmpp, callbridge - Outbound calls Domain *.* SIP Proxy: cucm.domain.local:5061 Local from domain: conf.domain.local Trunk type: Standard SIP Encryption: Auto - Call settings SIP media encryption: allowed - CallLegProfile Name: sipMediaEncryptionRequired sipMediaEncryption: required - coSpace CallLegProfile: sipMediaEncryptionRequired
