[RocelyRomero3104]

I replace a router ASR for  a ISR 4431, and  need this funcionality

Hello,

as far as I recall, the ISR 44xx does not support the gatekeeper functionality at all.

[RocelyRomero3104]

What functionality replaces the gatekeeper in the ISR4K, should I buy an
additional license, what should I do?

[Georg Pauwen]

Hello,

the 4431 supports the Integrated IP PBX ( Cisco Unified Communications Express) and Session Border Controller ( Cisco Unified Border Element, or CUBE). You need a 'Voice' license (check Table 5 of the attached datasheet)...

I have ISR 4431-V with IP Base + Unified Communications: CME, SRST, CUBE, I
need a configuration guide, where I am guided on how I can convert the
gatekeeper configuration to CUBE or what I have to do

Hello,
