Support Services - Why cant I see PJSIP extensions in the Sangoma addon module for freepbx?

While using FreePBX 13 and the Sangoma addons module for FreePBX you may notice that only SIP extensions are available to add. 
Currently PJSIP is unsupported in the Sangoma addons module for FreePBX, PJSIP can still be configured manually via the Asterisk configuration files, before doing this you will need to remove the Sangoma addons module from FreePBX.
