I’ve googled a lot, and searched this site & others, and so far, no joy !
I am trying to have
- a * box behind a nat router
- sip clients anywhere (same network as the *, or elsewhere)
- a voip provider in the world (other network)
everything works fine with IAX clients and SIP provider, but I like challenges and want to have clients running under sip (more soft/hard phone choices)
in the sip.conf,
When I put in the [general] section:
and in the [VOIPPROVIDER]
==> the SIP client can register, but the VOIPPROVIDER is reported UNREACHABLE - but I can dial a local extension (hello world) and hear correctly
if i comment out the externip and localnet, then the VOIPPROVIDER can be reached… but no voice can be heard
(yes, rtp.conf & ports on the firewall are opened - cf previous test)
What I am missing here ???
Your help will be greatly appreciated
