ISR 4321/K9 with Cube

[John_Webster]

Hello,

Do I need add CUCM with CUBE to get CUBE to work. I am new to Cisco SIP and not for sure if I need to add CUCM 

Thank you

Cube is just an SBC, session border controller. It can be used to connect with an ITSP to most phone systems. As long as you can create a SIP trunk between the phone system and the Cube.

Would recommend you to post your question in a new post instead of asking it on a prior post that has a completely different OP topic and is marked as answered.
