So: if you want to remove your telco's telephone service from your house wiring, how that's done depends on how your house was wired. If you attempt to connect your OBi's PHONE port(s) to the combined DSL/voice wiring, it won't work correctly. We can't tell you exactly how to re-wire things because we're not there, looking at your demarc box, etc. You'll have to figure it out.
I may be wrong, Steve, but based on his 2 posts I think he may have a naked DSL connection.

When I had a phone line, they were in different floors- 2nd flr and basement.
Thanks; that could be. It wouldn't change the issue of how to wire in the OBi to the house wiring: the DSL signal would still need to be confirmed as removed from the house wiring, or filtered to prevent the DSL signal from interfering with the OBi. If it's naked DSL, all that means is that there is no telephone-company-provided ~100VAC ring voltage to worry about and remove at the demarc, because the telco turned it off at their central office, right?
The problem is, we have no way to see how the house is wired, without being there, with test equipment, and I wouldn't want to guess and be wrong. The safest, and easiest way to deal with it would be to insert DSL filters inline with the OBi's phone ports -- the filters don't hurt anything if there is no DSL there to filter - they are simply low-pass filter networks. The better approach is to isolate the wiring from the telco to the DSL modem on a separate run of wire, not connected to anything else in the house. That's how my telco wired my house for DSL many years ago, before I replaced it with FiOS.
Hopefully, the OP now has a better understanding of how things work, and can ask more questions and provide more information, if necessary.
drgeoff:
For clarification. The filters do more than prevent the high frequency DSL signals interfering with phones or OBis. Having the DSL signals 'loaded' by any equipment additional to the DSL modem is a sure-fire way of crippling the DSL speed.
Even with filters between each wall socket and phone, the house wiring to those sockets is still able to act as an antenna picking up interference. And it can cause impedance mismatches and reflections further hampering the DSL. If maximising the DSL speed is a priority (possibly because the speed is low) it is best to have a single filter as close as possible to the point where the telco line arrives and have all house phone wiring fed from the 'phone' output of that filter.

Issue#1
Called my ISP and they said I have Dry DSL. The phone jack to the modem does not require a filter. Are you suggesting I should put a phone filter between the wall jack and the phone base unit?
Issue#2
All the cordless phones ring but we can only listen to one at a time. E.g. If she picks up and then I pick up, she will hear incoming voice, but I dont.
Thanks for all the replies =)

Re issue #2.
That is normal for DECT phones, but there is often a way for another handset to join an existing call. Consult the handbook for your phones.
MurrayB:
If you have Panasonic DECT 6.0 phones hit the CONF soft key and the the handset will join the conversation.
