SIP peer invalid content type 'multipart/mixed' with Nortel CS 1000 RRS feed

  • Question

  • Figured I would start a new thread on this question in case it was lost in a previous discussion on the CS 1000. We have a Nortel CS 1000 and are getting this error when we place a call from a standard phone that routes to the Speech Server 2007. The Trusted peer is setup for the CS 1000.  Not sure what this invalid content type multipart/mixed means:



    The Telephony Manager declined a call with Call Id '19a7b758-3d688e2f-13c4-40030-5009ab-4bc2319d-5009ab' for the following reason in component telephony session: 'The media description received from the remote SIP peer has an invalid content type 'multipart/mixed'.'. 


    Further trace information for support personnel follows:


    Microsoft.SpeechServer.Core.InvalidMediaException: The media description received from the remote SIP peer has an invalid content type 'multipart/mixed'.
