Hello, I have one grandstream 4024(with 2 accounts on it) one gpx2000 and for testing purposes one softphone. When i make calls from softphone to 2000 and 2000 to softphone i can see the clients are using reinvite and no traffic is passing thru asterisk except authentication stuff.. And also 2 accounts on 4024 are calling eachother with reinvite.. But if other clients calls 4024 all calls passes thru asterisk as i monitor with tcpdump.. all accounts has reinvite option enabled.. And all devices are on same subnet.. What can be the problem??? Any ideas?
