Cisco 3905 phone is hung intermittently, cannot be dialed and dial out any number. I am facing this issue from last months. Please suggest me how can i resolve this issue.
It is affecting only two phones and hung intermittently 110 -15 days. I also replaced phone but geeting issue only this Lan port. current firmware version is CP3905.9-4-1SR2-2 and did not try to upgrade. I think is it might be LAN port issue.please suggest me
If the issue is isolated or confined to two switchports only and any new phone connected to these ports faces the same issue then you need to compare the switchport settings off these two ports with the good working ports and check by replacing the cables connected to these ports as well.
