I need to integrate Cisco SPA50x Phones IP with CUCM 8.0. But, I don't know what license (DLUs) to order: if LIC-DM-DL or LIC-3PTY-DL, because I don't know exactly if CUCM will be recognize the SPAs like Cisco IP Phone or third-party phone IP. In addition, how many DLUs each SPA50x will be to consume. Could somebody help me with this questions, please ? I need to know this with urgency.
Since this moment, I'm very thankful for who can help me.
