Many thanks for your replies.
Sorry, I made a mistake trying to explain my problem.
I should have said that I want to forward calls
directly to my Sipura adapter i.e. <number>@<my domain> (
not <number>@internode.on.net)
I
know that direct i dialling works because I've tested it.
(Nodephone indeed doesn't accept forwarding)
So when on VoXaLoT I disable Call Forwarding then I get the Mailbox/User "unavailable". If I enable Call Forwarding to <number>@<my domain> then I get a busy tone.
If I call directly my phone (from another location, using a softphone) it works.
Is VoXaLoT using the SRV tag ? (I am with DynDNS which doesn't provide this).
What do I miss ?
Cheers.
