These Cisco IP phones are a pain to setup. I was given the task to setup 6 Cisco IP phones. Out of the batch 2 did not boot up to the point where we could access the settings. On the Cisco 7940 we received TFTP timeout o / A and just remained there. The other was a Cisco 7960 and gave an error Application Protocol Invalid. I was able to recover the phones by doing the following:
CAUTION: The instructions configure phone to work as SIP Phones not Skinny SCCP.
You will need the following:
- TFTpd32 http://tftpd32.jounin.net/
- Cisco IP Phone firmware (I used P0S3-8-12-00) http://radiotwenterand.nl/~graver/cisco/SIP-7960/P0S3-8-12-00.zip
- Cisco IP Phone configuration files http://www.minded.ca/default/wp-content/uploads/2009/12/Cisco-Config-Files.zip. If you do not know how to setup config files, check out the site http://www.minded.ca/2009-12-16/configure-cisco-ip-phones-with-asterisk/
- Download TFTpd32 at http://tftpd32.jounin.net/ and firmware and configuration files.
- Grab a computer and install TFTpd32. Unzip firmware and configuration files to a folder. To be safe, setup configuration files to have SIP[Phone MAC Address].cnf and SEP[Phone MAC Address].cnf.xml (Check website above if you don't know how to setup configs)
- Disconnect computer from network and plug into switch (Switch should only have computer and phone. Leave Cisco Phone powered off while you setup TFTpd32)
- Set the computer IP address to 192.168.1.1 MASK 255.255.255.0. Bring up TFTpd32 and go to settings.
- Under Global Tab, only enable TFTP Server and DHCP Server.
- Click on TFTP tab. Set Base Directory to the location of the folder where Cisco IP firmware and configuration files are. Set TFTP security to none.
- Click on DHCP tab and set IP pool starting address to 192.168.1.2. Set pool to 5 or something like that. Default router put 192.168.1.1 mask 255.255.255.0 Additional option 66 in small box and ip 192.168.1.1 in the box next to it. Uncheck Ping Address before assignation and Persistant leases.
- Hit OK and Restart TFTpd32.
- While your TFTP is running, power on the Cisco IP phone. If all goes well, TFTpd32 will log the connection and show the files it requests.
- The phones will show upgrading firmware.
- Phones should now boot up completely once installation is complete.
