Hello,

do someone know if there are VoIP to ISDN telephone converters ? I know
there are VoIP to Analog Phones converters to use your old analog phone
equipment over VoIP, but the same for ISDN (prefereable Euro-ISDN, DSS1, but
all other also ok) ?

Regards,

Martin

In Germany the most poular Voip to ISDN converter is the "Fritz!Box Fon WLAN
" produced by AVM.

If you would have a look at a german newsgroup you would see that any 2nd
treat is about this device (the call it the FBF or the FBF 7050) - see
news:de.comm.interent.telefonie

This device is a combined DSL modem + router + wireless acces point + Voip +
ISDN/analogue phone switchbox ...
It contains 1 internal S0 bus (where you can connect your existing ISDN
switchbox, or up to 8 ISDN phones)
There are also 3 analogue phone connections, 2 network (RJ45) and 1 USB
connection for your PC's and/or LAN ..
On the incoming side you can choose between 1 analogue or 1 ISDN line
On the VOIP side you can have multiple Voip accounts.

The most common set-up for ISDN users is to connect the "FBF 7050" between
your incoming ISDN line (NTBA) and your ISDN house installation. Then you
can contuinue to use all your existing equipemnt (both analogue and ISDN)...
Depending on the numbering rules you can setup to FBF to divert calls to
VOIP or PSTN...
Incoming calls (Voip, ISDN, fax) can be flexibely redirected to internal
phones or MSN of choise

I'm living in Belgium, and closely watch the VOIP discussion on 2 worlds: UK
and Germany ... What surprises me the most is that - despite the
globalisation - it looks like 2 complete different worlds if you read de.
and uk. newsgroups....
(Only common problem is sipgate ;-)

I've ordered one of these from 1&1.

I live in Germany and, since I am not aware of a German group, have been
following this one. What are the main differences between the UK and
Germany (apart from the prices---I'm assuming that, like everything
except wages for most people, they are higher in the UK).

a German VOIP group is: news://de.comm.internet.telefonie

I believe the main difference could be the ADSL connection, where basically
there are 2 standards:
"ADSL over ISDN" (also "Annex B", or "U-R2"), and "ADSL over POTS" (also
"Annex A").
POTS = 'Plain Old Telephony System'

In Germany you allways need a "ADSL over ISDN" Modem, even in the case you
have a analogue T-NET subscription, where in Belgium (and I guess in the UK
also) you would need a "ADSL over POTS" Modem

The Fritz!Box can be switched between Annex A and Annex B, see
