2 Handsets sharing single sip account

[rich_ng]

I bought the W60B as well as an extra handset.

I want a single sip account to be shared between the two handsets so that incoming calls ring both phones..both phones hear notifications of the same voicemail box and see the same call history where applicable.

Basically I want the two handsets to function like a traditional cordless phones with 2 handsets.

I think I understand that one handset will not be able to barge in on a call in progress, but if I am mistaken, I would like to know how to set this up also.

Right now, when I try and register both handsets to the same sip account, only one handset rings. The wierd thing is, the phone that doesnt ring still displays the missed calls.
