I have linksys pap2t VOIP adaptor which uses SIP protocol In its configuration 5061 and 5062 ports are bind for two voip links.
I have open ports using /etc/shorewall/rules
DNAT net loc:192.168.x.x udp 5061
DNAT net loc:192.168.x.x tcp 5061
But when I tried to call my voice not reached to other end I am able to hear voice from other end
If I bypass shorewall this VOIP device works perfectly.
Is there any other port or kernel module i need to install?
