Hi, I've currently got an Asterisk server running at home but want to switch to FS on my external server (located in a DC). Configuration: - 2 SPA3102 connected to 2 PSTN lines and 2 phones (on Line1) - Couple of voip phones The Asterisk server is running on my local network as are all the other devices; everything is connected to a DSL-router with NAT. The SPA3102 are configured as Trunks in Asterisk with the following configuration: allow=ulaw canreinvite=no context=from-trunk disallow=all dtmfmode=rfc2833 host=dynamic incominglimit=1 nat=never port=5061 qualify=yes secret=trunk1 username=trunk1 type=friend The SPA3102 are configured to register their PSTN-line to the Asterisk server. Outbound routes are configured to use 1 of the 2 Trunks. I want to do the same thing with my FS running on a server in the DC. I've setup all the devices and can make internal calls. Inbound calls on the PSTN lines are also forwarded to the correct voip-devices. I just cannot figure out how to configure outbound dialing to the PSTN-lines. The Wiki (http://wiki.freeswitch.org/wiki/SPA3102_FreeSwitch_HowTo) shows I should configure them as following: <include> <extension name="To PSTN"> <condition field="destination_number" expression="(.*)"> <action application="bridge" data="sofia/internal/${destination_number}@[IP address of SPA3102]:5061" /> </condition> </extension> </include> The problem here is that the SPA3102 are behind my router so the only possibility would be to setup some port forwarding to on the router with different ports for the 2 devices. I would rather not do that so I was wondering if there is an easier/better way to do that. Any ideas? Rgds, N.
