[Freeswitch-users] incoming DID, small talk with operator then transfer/forward call to extension

Hello. I've searched wiki and other websites but unfortunatelly did not find info or pointers how to resolve this issue. I want to achieve below solution. When incoming DID call occur person assigned to this line can pick a call and speak with customer, then she can forward/transfer call to another local extension or to GSM number. I've found solutions when I can forward call without answering it by operator but this is not the case. I've sucessfullly implemented gsm_open but sadly didn't find any information about transfering active call to next extension. Would you be so kind and show me the way how to get this working ? Thank you. -- Regards Tom
