UTM5 Problems with SIP VOIP
Hello all,
I try to set up a SIP environment but don't succeed. The setup is the following:
I use a AVM FritzBox 6360, which acts as cable modem and has an inbuilt SIP PBX. Attached to this box is a Netgear UTM5 with firmware3.52-14. Behind the UTM5 is my NATed internal network. In this network, I have some Android and IOS boxes with softphones installed.
The softphones register successfully with the Fritz PBX. The softphones can all out, but no voice data comes through, i.e. in both directions the call remains silent.
From the outside, signalling to the softphones does not work.
I already tried to enable/disable the ALG gateway settting, no change. I disabled the UDP flood block, no change.
I am really running out of ideas, especially since the setup worked perfectly nice with the old firmware 3.1.1-31. Anybody has an idea?
