Are you using SER or some other SIP proxy or an experimental branch of
the sip code?  Unless something has changed recently (and it may have
as Olle has really been working on new SIP stuff), a SIP user can have
only one registration.  You can register from multiple devices, but
only the one that has most recently registered will receive calls.
Put another way, when the second device registers it will unregister
the first device.

If it fits in with your plans you may want to give the softphones
different SIP usernames, and just have the dialplan ring them at the
same extension.  E.G:

exten => 100,1,Dial(SIP/FIRST-DEVICE&SIP/SECOND-DEVICE)
