Hi guys! Just wanna ask if you have any idea of what could be the problem when all local calls to any other extensions are being forwarded to a single extension? I checked the forwarding rules of these extensions but I did not see anything suspicious. I checked the phone status and they are available. The only suspicious thing that I've seen was the unsupported firmware. But I don't think that was the issue. By the way, the phones are T19. Thanks.
