Who can recommend hardware for Sparvoip to me and which attitudes is to be made.

Are grateful for each advice of the experts.

At present I use Sparvoip over their Softphone and it fold completely excellently.
However the whole would complete gladly over cord lot telephone. Is present a D-left rout the 715 P+, which would have exchanged werdeb. A far Gigaset 4035 similar to plant with 2 hand attachments, which over my ISDN runs. For ISDN I have one ascom Eurit plant. PC over DSL.

If someone lives in postal code the area 37, I could be helped gladly, natural against appropriate remuneration.

Moin Manfred clock,
welcomely in the forum.

Since you have ISDN and probably further to use want, too many devices do not remain: AVM Fritz! Box 5012, 5050, 7050, 7170. At present in the trade available however only 5050 and 7050 is, for the two different would have you our flea market or Ebay to plan.
To the CeBIT could still further interesting products to it come.
