Hi ,


we faced the dotted circle problem in the 7942 phones.


I tried some of the troubleshooting methods , but no luck


1) Restart the tftp server


2) tried with the tftpd server ( with option 150 & DHCP )


       tested more then 15 times, Phone detect tftp , when it trying to download the termdefault.loads , it went to dotted circle mode.


we tried with the firmware versions 8.5(4) ,8.5(3) ,8.4(3)



Any other way to resolve this ?


Thanks
