Alcatel Unleashed

I managed to use the Telnet command from Windows CMD and to enter the phone. but I have searched the whole forum but I have no more information than that. I will need the binary for the 4028 and the manipulation to load it from telnet.

No, the firmware can't be loaded via telnet.
You need to enable a syslog server and send all data from that phone to your syslog server.
I think the command was netlog, please test.
Another option is as said via Wireshark, capture the traffic from that set and see what it is trying to do.
I think you are already in sip mode but need to configure it correctly.
Without logs no real clue about it

If you go back into the soft infos menu, do you see a SIPc version? If you don't then your phone might not support SIP. Since you got a TFTP error it's the flashing that fails, if it was the sipconfig file you would get a HTTP error.

And yes, it is the netlog command

I got the binaries for the 4028 and I want to load them into the phone but I can not find the procedure in the phone
help me

my file this names
datsip4028G
noesip4028G

I managed to download these files on the phone via telnet and the command "dwl go sip" all this telechagre but when I restart nothing changes when I start the phone and I go in the settings nothing has changed

What does the "APPLICATION=" string say in your lanpbx file?

You should also put the binary files on you tftp server, not the phone itself. As far as I know iptouch phones can't flash from their own memory.

It also seems you might need main NOE version 4 or higher to boot from SIP

Have you done all of this, in addition to the option 66 and 67 stuff?

If you don't know Hex here is a few tips: you don't actualy write the "0x", the ip adress will be in 2*4 blocks hence the two symbols per part of the ip adress. So "172" would be "AC" and "10" would be "0A", check out the wikipedia page in english it has a nice chart.

So how this was fixed at the end? Could help others

4028 are working well with 3CX? No problems with registration expire time?
