  • Question

  • Hi Volks,

    We want to be able to use the "Call Voicemail" button in MOC 2007 R2. Unfortunately we always get the error id 504. When we call the UM by a landline phone we're able to place a voicemail or the get our voicemails. Can anybody shed some light into this? Is there a place where we have to tell the OCS Server the UM Server? The VoiceMail URI is set to Firstname.Lastname@domain.com in the MOC. The SIP address in the UM is the same. So, in my opinion this means that the MOC is unable to connect to the UM server, i'm right?

    kind regards,

  • Hi!

    i was able to fix this issue, the problem was that the dialplan in UM needs to have SIP secured instead of my old setting none. Furthermore i had to disable the TCP Offload on my network card (i got this info after using wireshark for sniffing the traffic).
