Thanks for answering this person's question. Could I ask a few.
When dialing like that (from ATA 186 to ATA 186) without a proxy
server and directly to an IP, should you hear a dialtone when you pick
up the phone that is connected.
And when using a SIP proxy server how does one go about dialing a
numer. For example I was given something like this to call someone.
And do I even need the SIP proxy setting to call this person as the
SIP proxy he gave me to use is '111.222.333.444'.
Is it just me or is there very little clear information out there
about this stuff for actual users?
And thanks for the information on NAT firewalls. I should have done
this long ago as I have had these boxes for a few months now. Time to
pick up some more for family and friends.
