VS-AGU-E2M0800 incoming call not working

Create trunk with anonymous credentials to my Freepbx vm. Create route in gateway (VS-GW1600) and from fxp to trunk and from trunk to fxo. Voip phone can receive external calls, but can't call to external. On gateway (VS-GW1600), i can see
-- Executing [2927364@default:1] Goto("SIP/192.168.206.2-00000033", "sip-102,2927364,1") in new stack
-- Goto (sip-102,2927364,1)
-- Hanging up on 'DAHDI/2-1'
-- Hungup 'DAHDI/2-1'

Hi
Can you prepare remote access and add my Skype:[email protected]. I'll check it for you.

Thanks to tiel.wen, i realized my mistake in configuration.
Based on the instructions found on the Internet, I tried to configure trunk for each fxo port.
but all i need to do is create one trunk, config inbound route did number plan and outbound route on freepbx side and Advance Routing rule - Caller_Dial_pattern - Filter_callerid (my internal extension) for outbound call on openvox .
