Before using the Cisco Unified IPPhone models 7911G and 7906G with Cisco Unified CallManager release 3.3 orlater, you must install the latest firmware on all Cisco Unified CallManagerservers in the cluster.

The 8.0(1) firmwarerelease has been made available on Cisco Unified CallManager installation CDs;however, it will not be made available on Cisco.com due to additional bugsfiled during final testing. Cisco recommends that you instead use the updated9.0(3) firmware load,which is now available on Cisco.com. This recommendation is limited to thisspecific firmware release and has no bearing on any other software or firmwareavailable on Cisco Unified CallManager CDs.


Cisco 7911g Sip Firmware Download

I have some old 7911G IP Phones which I need to get some firmware for. I know they are end of support from Cisco. I'm assuming that's why I can't find anything for them through Cisco's software download.

At a very high level: You'll need the appropriate firmware package and then to build the XML file so the phone knows what firmware files to download. Once that's done you would then need another XML file to tell it about the SIP Proxy. Note that the phone is not strictly RFC3261 compliant; it uses a bunch of custom Cisco behavior so your millage may vary.

Im mid way through migrating a site with 100 x 7911 telephones to a new callmanager and at least half the 7911's failed to register due to my firmware being too high a level to directly upgrade. I need to do an stepped upgrade to complete but I need to get firmware version SCCP11.8-3-3 to do it and for some strage reason cisco have locked old telephone firmware downloads and cisco TAC are being really un helpfull, so is there any one out there who can send me the firmware?

Before using the Cisco Unified IP Phone 7900 Series Firmware Release 9.3(1)SR4 with Cisco Unified Communications Manager, you must install the latest firmware on all Cisco Unified Communications Manager servers in the cluster.

If you are using the Cisco Unified IP Phone Expansion Module 7914, you must upgrade the expansion module to firmware release S00105000400 before using the phone to support relevant features on your expansion module.

Before you use the Cisco Unified IP Phone Expansion Module 7916, you must load the expansion module with firmware release B016-1-0-4-2 before using the phone to support relevant features on your expansion module.

Before you use the Cisco Unified IP Phone Expansion Module 7915, you must load the expansion module with firmware release B015-1-0-4-2 before using the phone to support relevant features on your expansion module.

I did a factory reset on the phone and It loaded up to the firmware update page. It shows my MAC address and updating progress. It sits there for a few minutes, quickly flashes term61.default.loads (two times, I believe) and then begins a reboot cycle. I thought that might be normal, so I let it go, then it repeated the process. I have not shut the phone off since the firmware upgrade.

I'm converting a bunch of Cisco 7911 phones over to the SIP firmware. I've got a working mac config file that provisions the phone. However, the 7911 requires a second softkey xml config file that tells the phone which softkeys are enabled on the phone, i.e. hold, transfer conference. Without it, all you can do on the phone is send and receive calls. I found the reference for the file in the mac config and found an example softkey xml file. I referenced the file name in the mac config and placed the softkey xml file in the same folder with the mac config. The phone picks up the mac config but appears to be ignoring the softkey xml file. Has anyone been able to get a 7911 fully functional with the SIP firmware and softkeys using mac config xml files and TFTP?

I verified in the internet and i think that the pb was that you we were upgrading from an old version from my version i tried to upgrade from SCCP45.8-3-2S to the one proposed in this article.

please could some one help with links to download the good firmware ? i have not a cisco subscription.

I have tried to use this method to install sip firmware on a Cisco 7911g and the update seemed to go well. with the phone registering and making outbound calls.

however i have a few problems. first of all the phone shows a very brief error when booting (too fast to read anything except error cache). also the phone always requests files from the tftp server on initial boot. if the tftp is not running it just gets stuck on registering screen. final problem is that there now appears to be no web portal to access the phones settings.

do these seem like symptoms of bad install or are they inherent with the firmware?

I have loaded the firmware for a 7911 from your site. Once the fimware is loaded, I can not edit SIP options. In the configuration for SIP I can scroll through the options, but SELECT or EDIT softkey do not appear.

We have been trying this for a week to register cisco 7911G with Asterisk 1.8 but nothing was helping. This article worked like a magic for us. The trick of putting nat = no under user context is amazing!!!!!!! THANK YOU SO MUCH

I too have purchased a 7911g in the hopes of getting it working with sipgate, but sadly not only are sipsorcery registrations closed, I have no idea where to begin with regard to what to put into config files.

You can factory reset a Cisco 7911(G) and 7941/7961(G) at boot time by following the procedure below. Performing a full factory reset will completely wipe the phone. This includes its firmware, leaving the phone in an unusable state if no TFTP server with the necessary files is available, along with a DHCP server that pushes the TFTP server (using DHCP option 150). If you have a Cisco Call Manager, this part should already be set up and the phone will simply download everything from the CCM. be457b7860
