hi all

9951 which is registered on cucm can call uc 540 user  but spa 504 phone which is registered on uc540 cant call to cisco 9951 phone gets error "unknown number"

How have you configured you UC520 to send calls to cucm.? The debug shows that the call is matching dial-peer 10. How is this configured? Is your UC520 configured in cucm as h323 gateway?

Please rate all useful posts

i have configured this dial peer 10 today for route calls to cucm for extension 2002 which is reg is cucm.yes uc 540 is configured in CUCM as h3232 gateway.
