I'm looking to see what options exist for checking the Unity Connection db to see if a mailbox exists before I send the call there. Currently in the Unity 4.0 platform, my IVR makes an SQL call to see if the mailbox exists and sends the call there if the box is in Unity. If it's not in Unity the IVR transfers the calls to the old voicemail platform. Now the customer is upgrading to Unity Connection 7.0 and I am looking for options to accomplish this. Can I make a SOAP call?
