I just did a UDP port scan using nmap on the LAN to my SPA3102 and found only UDP5060 used by Line 1 is available. I suppose UDP5061 is used by the PSTN Line but it is not available, is this normal or I missed something? I have both Line 1 and PSTN Line enabled. If UDP5061 is not available, how can I make direct IP call to IP:5061? Thank you for your kind advice in advanced.
Without knowing your detailed configuration, this may well be normal, it all depends on which account you have configured on the PSTN line and whether the GW functionality is enabled or not. If you would like to have further information, I suggest you take a look at the SPA3102 section of the SPA ATA Admin Guide,
