We have tested the Kirk DECT Gateway for internal use with we SIP
implementation. To set up the base station to work with Asterisk and to
register phones at a base station it quite a bit of work, but manageable.

Sound is quite good, in some cases too good. They shut down the mic
while you are not talking, to eliminate background noise while the other
party is speaking. The absolute calmness leads the other party to the
conclusion that the call was disconnected, very annoying.

The phones are quite expensive (up to €170 per unit + €600 for the base
station).

For this price we wanted an distributed phone book, maybe the base
station being able to look up the numbers in an extern ldap server.

Support od Kirk told us, that there some development in this sector, but
nothing ready for deployment.

After this conclusion, we have sent the kirk setup back und bought the
siemens S450 setup.

The Base station is limited to 2 concurrent calls, but if you only
register 2 phones per base station this is no drawback.

Now we have 5 base stations running with 2 or 3 phones per station for
less money than we kirk setup.

So far it works very good.

Although there is no solution for a distributed telephone book. You can
sent phone books to the telephone per web interface as an Vcard-File.

We are working on an automated solution that erases the phone in all the
telephones and sent new phonebook files to them.
