Interestingly I can call outbound to the WAN a SIP client registered with FS via Fring.  I wonder if Fring have some additional nat traversal/SBC malarkey going on as they proxy the calls.

I can't call outbound to an Eyebeam softphone registered directly wth FS though - although said Eyebeam is registered and can call inwards.

I must have my nat handling configured wrongly.

Hey Roly,

Are you getting anywhere?  I'm still struggling, I'm afraid.

I'm able to call from WAN --> LAN using the internal profile on port 5060, but I still can't call out from LAN --> WAN so there is obviously something really basic I'm still not getting.

In sip_profiles/internal.xml I have:


 <param name="aggressive-nat-detection" value="true"/>
<param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
<param name="ext-sip-ip" value="$${external_sip_ip}"/>

<!-- the external_rtp_ip etc being defined in vars.xml -->


In this example I have left <param name="force-register-domain" value="$${domain}"/> etc uncommented to force the registration to go to default.xml in the dialplan. 

I thought maybe this was my problem and tried putting a separate file in the directory to enable the WAN phone to register using the external DNS name for the server as its domain, and uncommenting force-register-domain, etc.  But then I got an error saying that the local (to Freeswitch) phone in the LAN was not registered when I tried to make the call from the WAN.

Any thoughts?

cheers
Bruce

Hi Roly,
 
I hope to be able to have a go at this later today.  I'll let you know what happens.
 
I have my FS box behind a hardware router/firewall, so I'm assuming I just forward SIP port 5060 from the WAN to the FS box and use internal profile, instead of using external profile with port 5080 forwarded as I have at the moment.  We'll see what happens.
 
cheers
Bruce

Ah I see... what? Please share and lead this blind man out the FS
wilderness!

I don't understand...what happens to the external profile? Do you delete it?
And how do you forward port 5060?

...and you thought you were a newbie!

Any insight would be much appreciated...loving the journey.

Ah I see.  I will try again using the internal profile and forwarding
port 5060.  Presumably still creating a directory entry to enable the
outside-facing domain to be used.

Many thanks for your patient help of a newbie Brian.
