Hi folks, I want to use a spa-3000 with freeswitch setup. The freeswitch box is on the internet, and the spa-3000 is used at home which access the internet via ADSL connection behind nat. I have follow the instruction as link below: http://wiki.freeswitch.org/wiki/SPA3102_FreeSwitch_HowTo Inbound call from PSTN just works. The problem is make a outbound call to PSTN via spa-3000. This line did not make any sense in my scenarios <action application="bridge" data="sofia/internal/${destination_number}@[IP address of SPA3102]:5061" /> as: 1. the WAN ip address is dynamic (ADSL) 2. the port is dynamic too (behind nat) so please advice. Thanks. -- Alex Chan
