Problem with outgoing calls

Hi. I’m having a bit of trouble with outgoing calls on zap channels. When i try to make an outgoing call asterisk doesn’t detect if the other party answers. When i run ‘show channels verbose’ in CLI asterisk tells me that the respective channles are in ringing state like this:

Channel Context Extension Prio State Application Data CallerID Duration Accountcode BridgedTo
Zap/19-1 agentie s 1 Dialing AppDial (Outgoing Line) 00726710704 (None)
Zap/15-1 int_omg 00726710704 5 Ring Dial Zap/g5/0726710704||T 00:00:14 (None)

although i can speak to the called party. I must mention that the context for outgoing calls is ‘agentie’:
My zapata.conf looks like this:
