B2B calls Spark to CUCM

Hi

We have Spark hybrid setup on our premise. But we are not able to call between CUCM registered devices and Spark (Outside ). I think what we miss is Expressway B2B. If so, any guides on the deployment ?

Maybe check the deployment guide in case you haven’t seen it step by step

In addition to the deployment guide that Srini already posted, you may want to check this doc on requirements for B2B calls to/from Spark:

I have already noticed the document.
