[Serusers] Setting up ser (configuring static forwarding)

[Ladislav Andel]

Hi,
you should better tell us where is your SER running . Inside of private
network? public internet? Is your softphone
in the same private network as your friend's softphone?
Could you draw your network endpoints eg.   SIP UA---(public
internet)---- SER --- (private network) --- your friend's SIP UA
If we know the location of your network entities then it would help us a
lot to understand what you are trying to do.
