Merging 2 siemens gigaset 4215 systems (one base with 2 phones + 2 phones)

Gino am doing darnedest to follow manual to a T - yet cannot:
1. Get base station to assign 4 different intercoms to 4 phones (have manually deregistered and manually registered) I get 1 intercom 1 and 3 intercom 4's - have tried to manually reassign intercoms but always end up with one 1 and three 4's
2. Get base station to allow me to set up answering machine (my old base station broke down so I bought a base station and 2 phones on ebay and am trying to merge with 2 old phones I had) all phones are functional - as would the base station appear to be - I have recorded announcement (not announcement only) have verified it recorded properly yet am unable to get "check" next to answering machine - get message saying "no announce only recorded"

3. When I move sattelite/remote phones away from base station to different part of my house they seem to lose signal - my house isn't that big believe me!

Any/all help is appreciated!

Kind thanks

Mark
