Hi,
I changed the Firmware from SCCP to SIP9. But I could not register. So I decided to use SIP8, but when erasing the firmware the phone decided not to take another. It just shows the message "Upgrading".
I checked (with ping and wireshark) that the phone gets the correct IP configuration, including option 150 (tftp). But on the TFTP server, nothing comes from the phone.
I used another system with CME and DHCP server on the router to try to get back to SCCP. But the same is true.
For some reason, the device is not going to the TFTP server.
Does anyone have any suggestions? Or can I discard the device?
Thank you.
