Cisco 7911g Sip Firmware
I bought a Cisco 7911G on eBay. It came with the SCCP firmware on it.
Cisco 7912 Sip Firmware
Unified IP Phone 7911G Expand All. This device has been saved to 'My Devices' list Cisco. 7911/7906 SIP IP Phone firmware. Aug 12, 2011 Cisco 7911G/7942/7945/7962 Phone with Asterisk Download the firmware (7911,7942, 7945, 7962) and extract it. Download and install/extract the tftp server.
However, I need to convert it to SIP. While trying to follow some instructions online, I cleared the SCCP firmware. Now, when I plug power into the phone, some lights blink, the MWI blinks, and then nothing.
Every few minutes this will repeat if I leave it plugged in. I desperately need help flashing this phone to SIP!!! I have the SIP firmware and all files. I have a t.f.t.p server and a standalone network just for this phone and a computer to program it. If anyone knows how or knows where some instructions are that will help me, please let me know!!! I have Google'd everything I know to. Thank you so much!!!
When a Cisco phone boots, the DHCP server passes the IP address of the t.f.t.p server to it. The DHCP server uses option 66 or 150 to advertise the t.f.t.p server's IP address. Now each Cisco phone is slightly different but here's the general procedure: The phone goes to the t.f.t.p server root directory and looks for several files:. a global file containing the version of firmware to be downloaded (xmlDefault.CNF.XML),. the SIP or SCCP firmware files (ex.
4 or 5 files like this one but with different extensions: P0.loads,.sbin,.bin. Sbd), P00 - SCCP and P0S or SEP are SIP. a file (SIP.cnf) with the MAC address of the phone in the name. another global file (SIPDefault.cnf) that contains info as to the registrar and Cisco password. The filenames are case sensitive and I've found that they vary from Cisco phone to phone and from version to version. I check the status messages when the phone is booting to troubleshoot.
Here's the write up that my students use to. And here's more info than you can shake a stick at about. The xml file can seem to be daunting but I've run them with little to no content as shown on the Cisco 7960 page, the defaults work fine for the most part.
