I know it's been asked before, but I can't seem to get my phone to convert.

Can anyone help?

Below is the list of files i have on my TFTP server. Phone is getting an IP from my DHCP and gets TFTP server's IP as an option.

I can see the phone (7960) go out and download files from TFTP, but eventually the phone would show TFTP time out.

OS79XX.TXT                (has one line inside P003-08-11-00)

P0S3-08-11-00.loads

P0S3-08-11-00.sb2

P003-08-11-00.bin

P003-08-11-00.sbn

Do I need any other files?

Can u try this?

Using wordpad, create a file called SIPDefault.cnf  with following contents.

Make sure you have correct .loads file on TFTP (here I am pointing it to

P0S3-08-11-00.loads. Put this file on your TFTP server.

# SIP Default Generic Configuration File

# Image Version
image_version: P0S3-08-11-00

Note: Make sure there is no CRLF or blank space after the filename

and there is exactly 1 space between the : and P (as shown above)

If it still fails, please upload tftp logs along with this file.

Most likely, you need to update to an intermediate version before.

Log files for CTLSEP000628954235 & CTLSEP000628956511 attached

see attached zip

With CME or CM, you should use SCCP, not SIP.

I need to convert them to SIP so they can be used with asterisk. Phones came from a CME environment, which I no longer have access to.

Which SCCP version do they have now ?

Try the corresponding SIP version.

it has 8.0 (8.0)

boot load id PC03A300

DSP 4.0(4.0)(A0)

Will try 8.0SIP

Just tried another phone, but failed again

looks like the phone is looking for XMLDefault.cnf.xml, which I don't have

Do a keypad reset sequence.

did that # on power up and then 123456789*0#

I created XMLDefault.cnf.xml with  a tag P003-08-2-00

now i am getting protocol application invalid on the phone

Still looking for help...

Saw Document ID: 67942

IP Phone 7940/7960 Fails to Boot - Protocol Application Invalid, but don't think it applies to my phones because they are running 8.0
