Hello. I need to understand the source of my problem with SIP trunk and Microsoft Exchange Server 2007 (Unified Messaging feature). I have a PBX Aastra/Ericsson MX-ONE that receive an SIP response 415 - Unsupported Media Type from Exchange UM Server.
Here the conversation packets when I try to call de Exchange UM from an analog extension: PBX > Exchange | INVITE sip:[EMAIL PROTECTED],user=phone,transport=tcp; (default port 5060) Exchange > PBX | 100 Trying; Exchange > PBX | 302 Moved temporarily; (because Exchange UM works with two processes) PBX > Exchange | ACK sip:[EMAIL PROTECTED],user=phone,transport=tcp; PBX > Exchange | INVITE sip:[EMAIL PROTECTED]:5065,user=phone,transport=tcp; (the port 5065 is for UMWorkerProcess.exe, on UM Server). Exchange > PBX | 100 Trying; Exchange > PBX | 180 Ringing; Exchange > PBX | 200 OK; PBX > Exchange | ACK sip:<UM_Server_FQDN>:5065,transport=tcp,maddr=<UM_Server_IP_address>; PBX > Exchange | INVITE sip:<UM_Server_FQDN>:5065,transport=tcp,maddr=<UM_Server_IP_address>; Exchange > PBX | 100 Trying; Exchange > PBX | 415 Unsupported Media Type; PBX > Exchange | ACK sip:<UM_Server_FQDN>:5065,transport=tcp,maddr=<UM_Server_IP_address>; PBX > Exchange | BYE sip:<UM_Server_FQDN>:5065,transport=tcp,maddr=<UM_Server_IP_address>; Can anynone help me?
