We use CUBE to peer with our vendor across a SIP trunk to handle incoming calls for our contact center.
On our end, in the DMZ, we're using CUBE. On the vendor's end, they are using a Sonus session border controller.
(Internally, on our enterprise network, we have a SIP trunk set up between CUCM and CUBE to pass on the incoming calls from our external vendor)
Our vendor is moving their equipment to a data center in a geographically disparate data center. They will be changing the IP addresses we are peering with.
Aside from making the appropriate access-list changes on our firewall and updating the ip address trusted list on our CUBE, are there any other changes we need to make make in CUBE or on our CUCM Publisher since it is just our external vendor that will be using different IP's for their session border controller?
