BT MeetMe issues with 380.66_4 and RT-AC5300

[RDO]

We use BT MeetMe for our company's audio conferencing needs. Unfortunately I am not able to join or host my meeting whenever I use my RT-AC5300 with Merlin at home. Doesn't also work with the latest Asus firmware for my router. If I bypass my home router and use my phone's data plan, I am able to successfully join and host my meeting. From the Connections log, I do see a bunch of udp connections with UNREPLIED when I try to host or join a meeting from the BT MeetME app on my phone or browser. These are the firewall requirements from BT Meetme: http://www.btconferencing.com/downloads-library/apps/dolby-voice/#firewall-required . I would greatly appreciate your help with this issue. Thanks!
