I have configured 7960 as SIP phone in my network and every phone has total 6 DN configured on it .Recently few ip phones in the network started showing cross mark on 2-3 DN line automatically and i will not be able to make any calls from that line during the time of issue.
This happens on random phones and once after i reboot the ip phone cross mark goes off and phones starts working normally. This issue happens randomly on different phones.
Also if i reboot the PC which is directly connected to IP Phone , the phone will go into "configuring IP" mode automatically and comes up normally.
Is it the proper behaviour.
Any help will be appriciated. i am also attaching the logs.
