Step1) Install chan_sccp
You can download the source code from http://chan-sccp-b.sourceforge.net/aboutus.shtml.
Note: For this test I downloaded Chan_SCCP-4.0.0_STABLE.tar.gz from their website and untarred that under /usr/src
go to the untarred folder and run the following:
./configure
make
make install
Add the following lines to /etc/asterisk/modules.conf
;;;; This is for cisco phones with SCCP
noload => chan_skinny.so
load => chan_sccp.so
Then configure the sccp.conf (in this example extensions 51 & 52 are used)
