I will preface this as I usually do that I am not a telecomms admin, so I am not well versed in Mitel or these systems, but with no telecomm admin here I am the person in charge of the system. We are having an issue with our Mitel system where we cannot make inbound or outbound calls. Internal calls work fine, external calls will work randomly, maybe for 5-10 minutes, then stop working for 30 minutes to and hour. We currently have no Mitel vendor as we had some disputes with them and ended our contract. We are looking into a new vendor but if there was anything that could be checked on our in that would be helpful. I did call Mitel and they checked some logs and according to them there was something about the PBX not answering the invites from the Gateway. Our network team has checked everything they know to. Would there be any additional steps to check the communication between the Mivoice Business PBX and the Gateway?
