9971 SIP Phones at remote location status REJECTED
I have 10 locations, Site 1, 2, ....10. All these locations have 10 phones each. These phone are configured with default SIP Profile. Were registered and working fine. While adding a subscriber I downgraded the cluster. After bringing back to regular version. I find all my phones status shows unknown.
I tried to change dhcp option 150 on dhcp router to point different server and reconfigured with the correct tftp ip address. Also I tried to shutdown the interface where phones are connected and bring it back up. Restarted tftp server many times. Even after all these I find my phones in REJECTED state.
I know personal reset on each phone will fix this issue. But is there any other way to fix this, since these phones are at remote locations.
