Cisco End of Life Products
Modulis customers and visitors, below are some end-of-life products for which Cisco announced End-Of-Life and End-Of-Sales notices:
Cisco Phones Compatible With Asterisk:
Today, most Cisco phones can be upgraded to SIP even if they are SCCP or MGCP. This list of phones includes models: 7940, 7960, 7941, 7961, 7910, 7911, SPA501, SPA502, SPA504, SPA509, SPA525, and more.
Note: The Cisco SIP firmware release is designed and tested to interoperate with the Cisco call control application only. Although SIP firmware is IETF RFC 3261-compliant, it is not supported by Cisco TAC or Engineering for use with non-Cisco call control systems.
Connecting Cisco Phones With Asterisk:
Converting Cisco CP-7960G VoIP Phone to SIP
Simply turn on the phone. Click on the Settings button:
Scroll down to Status:
Select Status, and then scroll down to Firmware Versions:
Under Firmware Versions, you will see following options:
App Load ID, Boot Load ID, Version, etc.
Focus on App Load ID: P0030800600. The third digit is 0, which shows that SCCP firmware is currently enabled; if the third digit is S, it stands for SIP. If the third digit is M, it stands for MGCP.
To perform the phone upgrade you will need a TFTP server, which you can easily download from Solarwinds or CNET. It’s a free download. The phone and TFTP server need to be on the same network to complete the phone upgrade. Phone firmware upgrade files can be obtained from the Cisco website; once you have the files, place them inside the root directory of the TFTP server. Within the list of upgrade files, there is a file named OS79XX.txt. It contains the name of the firmware that the phone will be upgraded to. Focus on the third digit in the firmware name; it should be an S.
Next, select Erase Configuration to erase all of the configurations from your phone:
Once Erase Configuration is complete, go to Network Configuration Setting and select Alternate TFTP option:
Still in Network Configuration, select option 8 and edit the IP address of the current TFTP server:
Once validated, the phone will start talking to our TFTP server and it will automatically pick up the SIP firmware that we specified on the TFTP server. After a successful upgrade, you will see SIP appearing in the upper right corner:
Next, go to Settings — > Status — >Firmware Version
As you can see from the Application Load ID: P0S3-07-5-00, the SIP firmware has been enabled on the phone. We can now use this phone with any SIP proxy or SIP provider!

Cost Effective Asterisk vs. Cisco
Asterisk is very cost effective as compared to Cisco products:
- Asterisk is open source; you can customize, edit, and modify its code according to your application requirements. Cisco is a closed-box application; no modifications or customizations can be performed with its applications.
- Asterisk does not require a license while Cisco products require a number of licenses; for example:
