[Freeswitch-users] outbound call with spa-3000 behind nat how?

11 Oct 2011

      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.
