[cisco-voip] CME to CM 4.1 Conference Call info

[Bob A. Bowie]

I have CME and CM4.1 installed.  When I create a conference from a CME IP Phone to other CME phones and CM IP Phones,
it works correctly.  However, when I conference from CM IP phones and conference in CME IP Phones, it connects, then immediately
drops the entire call and says "can not join calls".  Is there something onCall Manager I need to enable?  I am only using 2 CME phones and 1 CM IP Phone.

Thanks

  Hi Bob,

  Yes, that is the expected behavior. A call between two phones on the same CME will have RTP streams directly between the two phones. If the call is to another destination through the CME then the CME is used as an MTP device for the call.

    Hello, I have a remote site with CME 3.3 and my Call Manager Cluster 4.1.3 configured as H323 trunk
    through the WAN.  I have a question about call setup, as I am viewing the CME side with a packet analyzer,
    I see the CM IP phone stream to the CME router, and the CME router to the CME IP  Phone.
    QUestion: since these are both sccp phones on a WAN, I thought the media stream should be direct, once
    call setup is completed?  Is what I am seeing correct?
