I have an RVS4000 running firmware 1.3.3.6. I am trying to forward the ports for a Grandstream UCM6100 PBX. I have these configured but no audio on my calls. So I used PF Port checker and canyouseeme.org as suggested in this forum. The result the ports are NOT being forwarded. The RVS says they are but fails these tests. I am on Telus DSL with a static IP. No other routers on my network. Any help would be very much appriciated!!!
