Hi everyone. We have cisco CUCM 8.6 and C2951 router for gateway. We also have E1 for the telco line. It worked perfectly before. But now it can't call outside from the CUCM and also can't call from outside to CUCM. When i call to CUCM main number (telco number) it tells "The number you dialed doesn't dxist". What can i do right now? Where can i start? Could you guys please help
Thanks in advance,
