Hello comumunity,
i'm voip technician and my company today have a problem.
2 phones Cisco7841 when we try to call them, they go blank for a few seconds and then the phone is disconnected. On CUCM the phones are registered as well and are configured from many time. Now, since sunday 19/06/22 the calls in and out drop.
You have any idea?
Thanks for the support
