I configured expressway 12.7 with 1 ucm and 1 cups server.
as i checked the in https://cway.cisco.com/csa
all the configuration is okay and even it can login to device through the above tool.
but i cant login through any device(Windows,IOS,Android).
the tool show a specific error on UCM that i couldn't find the solution.
appreciate if someone could help me to solve the problem.
407 proxy authentication required.
I attached the error here.
as i searched through other forums it said that it may be due to not setting Do Not Check Credentials in traversal zone of both expressways.
i checked the configuration and it set to Do not Check Credentials.
all the services working fine on internal network
Appreciate if someone could help me founding the solutions.
