I can't find the paging module on raspbx

Hello ,
I wanted to make an IP based PA system.I found that the best way to do it is by using a Paging extension.I am using 2 raspberry pis as my SIP client and a Raspbx image on another Raspberry i as a PBX Server. But i can’t find the paging module anywhere.is it available on the rasPBX? or should i install it form some where…?
somebody help.

Are you talking about FreePBX? If so what version?

If you are using FreePBX have you tried going to Module Admin and installing the module? All module documentation is in the wiki http://wiki.freepbx.org/display/F2/FreePBX+Modules+Home

Connect to the rasPBX with SSH and click on the FreePBX Administration Icon, login.
On the top navigation bar click Admin, Module Admin.
Select the Basic Repositories and click the Check Online button.
In the second block of data (Applications) click on Paging and Intercom
Select the Download and Install radio button.
Near the top right corner of the page click the process button.
Confirm the download and install
When the process is done a ‘return’ link will appear at the bottom of the status window.
You will need to scroll to the bottom of the dialog to find the return link. Click return.
At the top of the page click the red Apply Config button.
Paging and Intercom should now appear in the applications menu.

Thank you for the responding. corrected the problem and finished my project. Thank you once again.FreePBX Rocks.
