Cisco 7940/7960 IP phones can support either the Skinny Call Control Protocol (SCCP) to run with Cisco CallManager, the Session Initiation Protocol (SIP) (refer to ), or the Media Gateway Control Protocol (MGCP), but not more than one simultaneously. This is possible because they load different firmware versions on bootup. This functionality is transparent to the end user, and you enable it through changes to the basic text-based configuration files that the phones download from a Trivial File Transfer Protocol (TFTP) server. Refer to for more information about a Cisco SIP IP phone. 1 LCD 2 Line or Speed Dial buttons 3 Footstand adjustment 4 Softkeys 5 i button 6 On-screen mode buttons 7 Volume buttons 8 Function toggles 9 Scroll key 10 Dialing pad 11 Handset Cisco recommends you have knowledge of these topics: • • SCCP—Skinny Call Control Protocol The information in this document is based on these software and hardware versions: • Cisco Unified CallManager 3.x and 4.x • Cisco Unified Communication Manager 5.x and 6.x Note: Make sure the SIP protocol is supported by the Cisco Unified Callmanager with the Cisco IP Phone model used for conversion. For example, SIP protocol for Cisco IP Phone 7906G and 7911G is supported only with Cisco Unified Communication Manager version 5.x and above.

Refer to the for more information on document conventions. Complete these steps in order to enable SIP functionality: • Download these files from ( customers only) and place them in the root directory of your TFTP server (tftpboot on a UNIX machine): • P0S30100.bin—This is the SIP image. Tekken 5 Iso Highly Compressed For Pc. Download the file in binary format, in order to ensure that it is not corrupted. Note: There are many different variations of this file, which depend on the version of software that you load. These are some examples: • SIP Release 2.3 or earlier: P0S3 xxyy.bin—The xx variable is the version number, and yy is the sub-version number. • SIP Release 3.0 and later: P0S3- xx- y- zz.bin—The xx variable is the major version number, y is the minor version number, and zz is the sub-version number. • SIP Release 5.0 and later: After this version is installed, you are not able to revert back to versions earlier than 5.0.

You can still change from SCCP images to SIP images, but they both must be version 5.0 or later. Refer to for more information. • This table describes the meanings of the first four characters in the binary files’ names: First Digit Second Digit Third Digit Fourth Digit P represents a Phone. 0 means that it is a combined image (application and DSP). Represents the phone Protocol: 0 for Skinny and S for SIP. 3 represents the ARM processor. Note: Choose Settings >Status >Firmware Versions in order to verify which image the phone uses.
