SIP trunk between Edge and Cisco Media Gateway - Content-type Not Accepted

  • 1.  SIP trunk between Edge and Cisco Media Gateway - Content-type Not Accepted

    Hi,

    We're trying to setup a sip connection between Cisco Media Gateway (with terminated ISDN lines) to Genesys Edge.
    On Cisco we have dial-peer's configured to route calls to Edge.
    In pcap logs we can see INVITE comming from Cisco to Edge, but its header it contains:

    Content-Type: multipart/mixed;boundary=uniqueBoundary

    And Edge responds with:
    SIP/2.0 488 Content-Type Not Accepted

    We think we should expect Content-Type: application/sdp from Cisco side (not sure this is the case). But we don't know how to change that content type for calls.
    We'd appreciate if there's anyone able to give us any tips on configuration Cisco MG to cooperate with Genesys Edge.

    Could not find info directly related to this architecture, but did find this doc about the CMG to Engage Media Servers, so it very close.  Configuring Cisco Media Gateway (genesys.com)

    Did you examine the SDP of each to see if there was a mismatch of codec, dtmf, etc?
