Hi, just to repeat my previous post (and trying to find a solution): Setup is * behind NAT. I can use FWD (time service, echo server) without problems when I add this to sip.conf: externip=a.b.c.d ; a.b.c.d is the IP of the router (Linux/Nat) outside_addr=a.b.c.d My ICH however now responds with: -- Got SIP response 481 "Call Leg/Transaction Does Not Exist" back from 213.137.73.140 If I leave the above section out, ICH works fine for outbound calls but FWD is quiet. I have yet to get inbound calls to work. So fix this scenario, my suggestion would be to change the * sources so that the externip/outside_addr variables can be set/disabled for individual SIP providers rather than globally. Regards Andreas
Andreas, below is my partial sip.conf (which is relevant for fwd) this works for me. jakob [general] port = 5060 ; Port to bind to bindaddr = 0.0.0.0 ; Address to bind to nat=yes ; externip = myhost.dyns.net ; Addr put in SIP messages if we're behind a NAT localnet = 192.168.10.0 ; Internal NETWORK address localmask = 255.255.255.0 ; Internal netmask ; ;********************************************* ; REGISTER WITH SIP PROVIDER ;********************************************* ; register => 54501:xxxx@fwd.pulver.com/1234 ; Register with FWD as 1234 ;********************************************* ; OUTBOUND SIP CHANNELS ;********************************************* [fwd] type=friend secret=xxx username=54501 host=fwd.pulver.com ;outboundproxy=192.168.69.247:5082 ; not sure if this is implemented canreinvite=no
