We currently have our Cisco Telepresence solution working well via a CUBE to a Tandberg Telepresence server, but we are unable to get a Cisco 7985 working via the CUBE. A CCSIP debug shows a "no sdp" error. This may have something to do with having "sdp passthru" enabled on the CUBE (?) for Telepresence. The SIP trunk from CUCM is just a basic default configuraiton.
The dial peers are also just basic configuaration (no codecs specified) - I've tried with "codec transperant" both on and off on the dial peers.
