When I add 2nd lines at the call manager and press reset phone at call manager, phone got hangs, and no response at all. And I have to unplug and replug in the lan cable to take effect, and the phone works normal then.
Call Manager: 4.2(3)sr2b
OS: Win Sever 2000
Phone: 7970G with "SCCP70.8-3-3SR2S"
Please kindly advice what else I have to look at to solve this issue. Thank so much!
