Along with our Cisco 4331 ISR I received a few white cardboard envelopes marked
Unified Border Element Enterprise License - 5 sessions. When I look at the
paper inside I don't see a serial number or something that I would register.
Am I missing something? Is this just kind of honor system as to how
many calls should pass at once through the ISR? See the attached
pic. I want to obviously avoid having the ISR fail during a period
of high SIP voice traffic.
