Hi
We have ISR4331-V/K9 router with 10 cisco ip phones connected to it, it was working fine without any issues the suddenly phones stopped working, my question is do we have to purchase a license to make phones work with standard features?
Thanks
Thanks for ur reply
My PC ip is 192.168.1.200 it's from the same switch range
When I change the default vlan from vlan number 1 to vlan number 300 and click on submit it will ask me if I want to proceed?
Then I click yes but nothing changed
