I've read to see if I find something similar to my case but I do not see anything, so I opened a new post. I am trying to register a polycom trio 8800 in CUCM 11.5 but I do not succeed, I already create the security profile, the user and the extension in the CUCM and I already put the data in the plycom and nothing. The polycom gives tone but it is not registered in the CUCM, the same I can not mark extensions. I already read the FAQ to see and I do not see anything either. the extension comes out with an "X" as seen in the image
