Cisco 7975 SCCP to SIP

[GbengaSogbetun5408]

Hello all.
I would like to apologize if this has already been answered (and if it has please direct me to the post).
I have several 7975 IP Phones that are currently SCCP. I want to convert them to SIP. I have a Sonicwall TZ210 router and plan on using a tftp server software on my PC.
Any help would be appreciated.
Thank you.

I presume you don't have access to Cisco CUCM/CUE, am I correct?

Hi Leo Laohoo, yes you are correct, I don't.

Ok, you'll need the following: 

1.  SIP firmware for the phones.  IMPORTANT:  Don't bother with 8.X firmware and go straight to the latest9.4(2)SR;

2.  TFTP server - Recommend you use TFTPd32/TFTPd64 (LINK);

3.  Working SEPmacaddress.cnf.xml file; and

4.  DHCP Option 150

In the SEPmacaddress.cnf.xml file, pay close attention to the <loadInformation> tag.  This is where you put the filename of the firmware the phone is meant to use.  Pay close attention to the syntax.  

Hope this helps.

Hi Leo Laohoo, thanks for the info, sorry for the delayed response, just got back from work.

i have followed your instructions so far, 

what do i do next? are there any special settings i have to configure on the phone before i start the process? are there any settings i have to configure on the TFTPd64? what is DHCP option 150 and how do i configure it?

Thank you.
