Queue still rings extensions after PSTN caller has hanged up on Grandstream GXW4108

Description:
Good day,

I have a GXS-4108 configured with 6 lines. I cant seem to find the firmware version but this is what I can pickup from the device:

Hardware Revision: Main-- 2.2 Rev A Part Number-- 966-00002-22A
Product Model: GXW4108
Software Version: Program–1.3.4.13 Loader–1.1.3.4 Boot–1.1.3.2

The “FXO LINES > CHANNEL DIALING TO VOIP > USER ID” is set to ch1-5:300;ch6:206;ch7-8:; Where 300 is a queue on Asterisk/FreePBX 2.11.0.0. This queue is configured to hunt for an extension (201,202,203,204 or 205) When I call any of the PSTN plugged into channels 1-5 the call goes to queue and one of the 5 configured extensions (201-205) rings. If I hang up the call, the call keeps hunting through the extensions (201-205) on a Grandstream GXP2160. The PSTN on channel 6 is calling 206 which rings and stops ringing when I hang up the call to the PSTN line on channel 6. If I configure each channel to call the extensions directly like channel 6 is doing, they all hang up ok.

the problem is only with this queue which hunts for an available extension 201-205 and when I hang up the call, the GXP2160 keeps ringing. Am I doing something wrong? Is this a problem on the Gateway, on the Asterisk or the GXP2160 configuration? I should add that this is my very first implementation.

There is another person experiencing this problem a long time ago it seems: http: //community. freepbx. org/t/queue-doesnt-hangup-even-after-pstn-caller-has-hung-up/15022 … He changed his setup to not use SIP channels which I dont want to to, he created the trunks on FreePBX which I would do but I as I said I am newbie and since this is my only problem I am assuming that I may be doing something wrong. I will add that, if I call the group (300) from an extension lets say 210… the 201-205 extensions ring fine and when i hang up the 201-205 extensions stop ringing.

The provided link is broken up as new users can not post links (even though this link is from this very forum). Sorry about that.

I have updated to the latest firmware version 1.4.1.5 and the same happens.
