Unfortunately I don’t manage the CUCM environment. Based on what I’ve read so
far, CUCM SIP Trunks technically only support SRTP or RTP, but not both, in a
SIP Invite. If both are present in the SIP Invite then CUCM only selects the
first one in the list as opposed to choosing a preferred type.
I’ve got a non-Cisco SIP device sending SIP Invites to CUCM (SIP Trunk). The
SDP from my device includes RTP and sRTP in the SIP Invite. Reading Cisco docs
it looks like the way Cisco expects sRTP to work is the SIP Invite should only
include sRTP assuming if the call should be encrypted. If
Yep, it’s TLS. Certificates are loaded.

Mark,
Is the device actually using TLS for the signaling? I don't think CUCM will
let you use SRTP if the signaling channel isn't encrypted.

Can you send a CallManager SDI/SDL trace for one of these calls?
