Hello Folks,
i have cisco system that is working since 2012 without any problems. Two months ago, i am facing problem with Cisco-CP9971/9.1.1 phones which unregister for around two days and then register. i check my configuration as it is still the same and found nothing. check my switches configuration also, no problems. here are some outputs for your reference, and if you need more i am happy to provide. thanks in advance for your valuable help.
All other phone types are working without problems
