How to increase number of extension over 100

Dear ALL
how can i increase number of extensions over 100 in the elastix or free PBx…can i make any changes in the related file (local files of Free pbx) i am using winscp…
any suggestions

FreePBX does not limit the number of extensions.

If there is any such limit in Elastix, it is not part of the FreePBX code.

When you try to add the 101st extension, what happens?

when i made extension over 40 it don’t appear on the panel…i want to see all the extension that i created in the panel

Which panel? FOP?

Buy the licence for FOP2 to achieve what you want.
