convert SCCP to SIP

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?

Re: convert SCCP to SIP

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.

Re: convert SCCP to SIP

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

Re: convert SCCP to 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.

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

Re: convert SCCP to SIP

I think my problem was SIPDefault.cnf  was named SIPDefault.cnf.cnf
