we have a vendor that wants to connect the responder 5 (Brekeke server) to our CS1K. They are asking for an IP address of our switch, but can not narrow down which IP Address (OAI gateway, , node, sig servers, switch). Has anyone hooked this up and can you let me know exactly which IP address I should provide them? The last thing I want to do is play a guessing game with 4500 active phones. Wireless phones are the Avaya 6120.. not that that makes a difference.
