I keep getting these errors sporadically on all extensions. What can it be.

The ucm is at the latest firmware and all gxp1628 phones are on the lastest firmware. The ucm is setup as a switch.


#3

All the gxp1628 are static ip


#4

Hrm… What’s your DHCP lease length?


#5

What does the network map look like? DNS server, Gateway, NTP Server etc


#6

The UCM and all the phones are static ip address’s. The is a router in front of the UCM


#7

what is providing the calls in to the UCM ?

I think it is because register in 1 packet is rejected. Then next one is ok.
Change on phone so it add register auth in 1 packet (i cannot find option in 16xx).

GXP21xx have this
Add Auth Header On Initial REGISTER: No/Yes
