We are merging with another company. Our current challenge is that we will be moving users to different locations before the merger is completed. and they would bring their current phones to the new location and we are on 2 different systems.
The acquiring company has a Mitel cloud phone service and we have a Shortel on premise service.
The routing between both companies will be in place this week, so we should be able to route the traffic. The phones are on different VLANS, So the thought was is that we would need to add the acquiring company's subnet and VLAN ID to our layer 3 switches in order to pass the traffic out of our network to the Mitel cloud and not to our local Shoretel PBX for service
Would this work?
