[Freeswitch-users] uuid_simplify or uuid_deflect in mod_callCenter

Hi, Can I use uuid_simplify or uuid_deflect in CallCenter config to route agent calls? I want to send REFER with Replace for Agent transfers as our agents are registered to a different PBX and FreeSwitch is just a gateway. REFER will remove FreeSwitch from the call path. If yes, can I get an example, I tried using it in CallCenter config but I get error cannot locate uuid_simplify or cannot locate channel uuid_deflect. Thanks, Varsha
