Sounds like CUCM is either finding an unroutable urgent priority match or the intended pattern is not in the Calling Search Space of the device.

Is the CSS the same as on other phones which can successfully call the number?

Check the dialed number analyzer using the CSS configured on the device (and line).

Check for any translation patterns or urgent priorities route patterns.


Are you using the @ symbol? If so, have you installed and chosen the correct Numbering plan?

CCM Traces would probably be helpful also.
