Dear Expert,
I have a UC520 and I am running into trouble with my configuration with SNR.
I have on my FastEthernet an AccessList - when I remove this, snr is working - but
I need this because FastEthernet is directly connected to internet and UC520 is
also the firewall for this customer - can anyone tell me which ports I have to open
so that snr is working? The call setup looks fine but I have no audio in both ways.
maybe anyone have an idea how to set up my access rule.
many thanks
Klaus
