There are many things in this world that are hidden just beneath the surface that make our lives easier.Whether it be the Secret Menu at In-n-Out Burger or the good old Konami Code, the good stuff that we need is often just out of reach unless you know the code.
Features The CP-7936-PWR-KIT powers the Cisco Unified IP Conference Station 7936 and the Cisco Unified IP Conference Station 7935.
Both phones can run either SIP or SCCP protocols – but you have to choose which firmware (SIP or SCCP) to have as both protocols are not built in to the phones and if you want the ‘other’ firmware you have to take out a support contract to download it from Cisco.
The 7905G can also use H.323, the 7912G includes a 7960-style Ethernet switch instead.
This is a known issue, documented in the release notes for SCCP firmware release 8.5.(2)SR1: For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(2)SR1 or greater, you must first upgrade your firmware to version 8.5(2).
Once you have upgraded to version 8.5(2), you can upgrade your IP Phone to version 8.5(2)SR1 or later.
