Hi, i want to connect remote softphones to our trixbox (freepbx flavor) but has experienced some troubles. inbound softphones/hard phones are working.

My situation:-

freepbx on a linux box -> adsl router (speedtouch) - internet.  all traffic is routed to the freepbx box.

freepbx server: i changed the sip_nat.conf as found on several forums (nat = yes; externip = xxx.yyy.zz  etc.)

added an extension with nat=yes, qualify = yes.

i used the softphone from express talk. the last log shows that the register request from express talk is done. the window of the phone shows that the server does not reponded. I know.

the server log shows that it cannot create a sip channel, reason unknown.

Does someone sees light in the dark? would be great.
Many thanks, AJ
