We use the Cisco CME 3.3 on a Cisco 2821 with IOS SP Services 12.4(3g).
My problem is that on the main phone, 7960 with 7914, the main dn always goes down. All other dn on the other phones working well and are in idle or connected status or so, but never down.
After a reboot of the router, the main dn is up again for some minutes...
Does anybody have an idea? Thank you for your help.
