I'm just getting the same error, 'TFTP Timeout' - whatever I do, even tried switching off the tftp server and i get the same error. So I'm wondering if the phone is actually connecting to the tftp server properly. It's getting an IP address correctly as it shows up in my dhcp clients. I'm using Mac os x tftp server. Any ideas?
I do have the dhcp option set in the bootpd.plist. This is what's written:
Try getting debugs from the switch, where the Phone is connected to
Just wondering if you could post the Switch Port Config from the switch where the IP Phone is connected.
The debug command for the debugs would run are:
1. debug ip tftp events and packets
2. I would also want to check if the DHCP as well as TFTP packets are being sent out at all on to the VLAN
I'm not using a switch, I'm connecting the phone directly to my mac, using os x server's DHCP server (with option 150 added to the bootpd.plist) and running os x tftp server.
The phone is getting an IP address and I can ping it. The tftp server doesn't show any log of incoming requests. The phone just says 'Requesting Configuration' for a while then says 'TFTP Timeout'
Here is the thing, usually Cisco IP Phones depend on the CDP to get the correct VLAN (Voice VLAN) and then gets the IP Address and from there it goes on..
I wonder if there is any possibility at all for you to be able to use a switch?
Without this, its very difficult to see, what the Phone is sending and if there is any Err at all.
May be the Wireshark can help?
Basically I'm trying to flash it to SIP so I can use it in a standard network (not with cisco hardware). I don't have a cisco router. Is it theoretically possible to flash the phone with my setup? I agree the inability to debug is very frustrating.
Also...do you know why the settings button doesn't work on the phone?
Yes, it should be possible.
Try **#, and see if it unlocks anything at all?
My guess is, when the phone was previously connected to the CCM Server, it was in a "Locked Down" config mode, hence nothing is visible.
Secondly, if that is the case, the only option is to update it with a default config file (and getting the old config erased).
Can you install CCM Server (in a VMWare Wkstn) on your MAC? If yes, then, there would another challenge, how to get the phone be able to talk to the CCM Server on a VM Wkstn on your MAC.. and if that can be done, you should be good :-)
**# doesn't work.. but the factory defaults does work. So it's been reset with the option to discard network settings. So I assumed it would have defaulted to finding the tftp server on the dhcp and searching for firmware flash.. but it doesn't
I'll read your suggestion a few times and see if I can do that... I do have a PC too so might give that a go next.
