Is that using LuxFibre or Tango's own last mile (possibly a P&T fibre
leased as dark fibre by Tango)?
This Tango package includes a fixed line phone number
which I
currently do not use.
As far as I know the providers have switched to SIP
generally, so I
wonder if, provided I know the connection parameters, I could set
any SIP-phone and use the fixed line which I pay for?
Yes, that's how the Fritzbox does it. You "just" have to extract the
correct SIP username, password, hostname, etc. Maybe from a working
(preconfigured) fritzbox, maybe by connecting the Fritzbox to a
GNU/Linux machine instead of directly to the fiber ONT and sniff the
DNS and SIP traffic.
Does anyone have experience setting up something
similar?
That's how my notes say it happens on LuxFibre lines; Tango might have
different VLAN numbers, but my guess is not. Again, configuration of a
working Fritzbox or sniffing the traffic will tell.
The SIP traffic goes to VLAN number 39, and you get an IP address by
DHCP. However, with my provider, the SIP server is perfectly reachable
over the "common normal" Internet connection, and I didn't easily /
quickly manage to force RTP traffic linked to SIP to go over VLAN
39. It was just easier to let it go over the normal Internet
connection, and that's what I did. Worked like a charm.
I now notice it doesn't work anymore. No IP address from DHCP. They
must have changed the configuration parameters without telling
me. That shows you how much I actually use that SIP line.
Maybe they don't use VLAN 39 anymore. Dunno.
