CISCO IP Phone SCCP to SIP
I have had no end of trouble trying to find ways to upgrade some CISCO IP phones from SCCP (Skinny) to SIP. The biggest problem I found was trying to find information. Here I list what I did to upgrade some CISCO IP Phones from SKINNY to SIP.
Prerequisite
DHCP
You network must be using option 66 for DHCP, which points to a TFTP server, either using IP or FQDN.
TFTP
There are a lot of articles that say not all TFTP servers work with the CISCO Phones. I first used OpenFTPServer as that was the recommended. I also used SolarWinds TFTP Server as that is my favourite for Windows. For Linux my standard is vsftpd.
You will need to make a choice of which TFTP server to use.
Firmware P0S3-08-9-00
Files
The following information is based on SIP firmware P0S3-08-9-00. It seems that you can only download old firmware form the CISCO web site unless you have an account/contract with CISCO. I called CISCO and said I required the latest SIP firmware. A help desk person made the files available to me. I may have been lucky.
Extract the ZIP file which contains the firmware files to the root of your TFTP server. These files should be as follows:
- OS79XX.TXT
- P0S3-08-9-00.loads
- P0S3-08-9-00.sb2
- P003-08-9-00.bin
- P003-08-9-00.sbn
OS79XX.TXT
Edit the contents of the OS79XX.TXT file. By default it will have P003-08-9-00. Change that to be P0S3-08-9-00. The S represents SIP.
SIPdefault.cnf
You will need to create a file called SIPdefault.cnf. The phone will look for the field image_version. You need to specific the firmware version that you would like to use.
NOTE: Not all phones used this field to automatically upgrade via TFTP. The CISCO 7912 phone requires a manual process. See that sections for more details.
image_version: P0S3-08-9-00
I would recommend that you use the SIPdefault.cnf file listed below. This will be a global file that you would like all of your phones to use.
configuration files
SIPdefault.cnf
This file will be used by all CISCO phones. Any non-global or specific configuration required for an individual phones needs to be placed in the file SIP<mac_address>.cnf. For Example, if the MAC address of your phone is 1C17D3C2FF93 then you need a file called SIP1C17D3C2FF93.cnf that contains the individual setting for that phone. See the next section for that information.

SIP<mac_address>.cnf
This file contains specific information for each phone. The information here is more about registration information to the PBX.
The following configuration file is for a CISCO 7940 which is a 2 line phone. If you have a 1, 3 or more line phone then add/remove the lineX lines appropriately.
# SIP Configuration Generic File (start) # Line 1 Settings line1_name: "8952" ; Line 1 Extension\User ID line1_displayname: "" ; Line 1 Display Name line1_authname: "8952" ; Line 1 Registration Authentication line1_password: "" ; Line 1 Registration Password # Line 2 Settings line2_name: "8952" ; Line 2 Extension\User ID line2_displayname: "" ; Line 2 Display Name line2_authname: "8952" ; Line 2 Registration Authentication line2_password: "" ; Line 2 Registration Password # Phone Label (Text desired to be displayed in upper right corner) phone_label: "Exten: 8952 " ; Has no effect on SIP messaging # SIP Configuration Generic File (stop)
dialplan
You will notice in the SIPdefault.cnf file there is a line that sais:
# Set Dialplan File name dial_template: dialplan
This is informing the phone as to where the dialplan or number pattern matching scheme is for the phone. My dialplan is based on Queensland Australia.
