Hi Michael, I had the same issue. It is quite easy: On the PBX behind the main AstLinux box set in sip.conf: ; NAT settings externaddr=xx.xx.xx.xx:5062 ; this tells the second provider to send the returning packets to port 5062! localnet=yy.yy.yy.yy/255.255.255.0 nat=force_rport,comedia Then on the main AstLinux box set NAT EXT -> LAN port 5062 to the IP of the 2nd PBX but on port 5060! Then just use different RTP ports then on the edge box.
