I've got a FreePBX / Asterisk setup at home with a Zaptel/DAHDI card for connection to the PSTN all working fine and dandy. I'd like to get my Android powered mobiles to use PBXes and setup a trunk/link whatever between my * and PBXes so that I may route incoming calls from the PSTN to the mobiles via PBXes.
The mobiles are happily working with Sipdroid to PBXes, but I think I've missed the clue bus for linking * and PBXes. I can get * to register to an extension fine, but neither inbound or outbound dialing works (I mean the call setup fails rather.than no audio).
My * is behind a NATting firewall if that makes a difference, it is a Linux based IPTables one with SIP helpers nf_nat_sip and nf_conntrack_sip loaded and is using UDP for the transport.
I've tried so many different configs with/without port forwarding I think I need a fresh start - could somebody please give me a known working config...
