Can't set "Max Wait Time" queue option


I am not able to set “Max Wait Time” queue option in freepbx. When try to setup no option is being written in /etc/asterisk/queues_additional.conf. I am using FreePBX

Same answer as in the ticket:
That is because it is written in the dialplan (extensions_additional.conf), this example shows that I have selected 6 minutes (360 seconds) for queue 2499:

exten => 2499,n,Queue(2499,t,,,360)

Thank you mickecarlsson, i got it now !!!
