I am using WNR 2000 cable router and Grandstream 486 and 502 ATA's for provision of Sipgate VOIP. I am getting cut off and speech transmission problems, although necessary port forwarding has been carried out. Notice WNR2000 has no ` DISABLE SIP ALG ' option that always solve any previous problems on earlier routers
