Over the last week there have been a number of people reporting that they can no longer call to certain local and long-distance numbers. Some of the numbers affected by this issue can get through to some of the numbers they are trying to reach and some 1800 numbers as well. The telco is saying that this is an internal issue with our UCM, but I really don't know what could be causing this problem. When I tested my line I wasn't able to call out when logged in to my profile, but when I log out I'm able to dial out from my extension without any issues. Any help with this matter would be greatly appreciated and let me know if there is any information I can provide that would help determine how this problem started and what the solution is.
Better to start with the dialed number analyzer to see if your or the numbers in question have access to the called number pattern.
