2 of my GXP2000 are dead. Blinking green light.

tcpdump shows them trying to get frimware from an old Grandstream server. I installed a ttp server on my linux pc and added that IP to the interface but the phone does not download the file. It looks like its requesting a different port than the one the server shows. This is the tcpdump output:

12:45:24.900114 IP 192.168.50.211.32875 > 168.75.215.188.tftp: 313 RRQ "boot55a.bin" octet blksize 1024 tsize 0 timeout 4 gra

12:45:33.002740 IP 192.168.50.211.32875 > 168.75.215.188.34887: UDP, length 4
12:45:33.002807 IP 168.75.215.188 > 192.168.50.211: ICMP 168.75.215.188 udp port 34887 unreachable, length 40

This is what I get on max debug from the tftp/dhcp server:

Any hope?
Thanks.

Solved

I changed the IP of my linux box to 168.75.215.188 as primary and reconfigured the DHCP server to give ip numbers on that range and it worked.
