SRTP calls between CMS and Jabber

Dear All,

 

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
   
Is there anything I missed?

 

Thanks,

Laszlo
