Hi Martyn,
I hate to jump in on Paolo's thread here, but I'm guessing that he may
have meant to get rid of the "overlay" setup altogether and just go
with "Shared" octo-line DN's
Feature Comparison by Directory Number Line-Mode (SCCP Phones)
Table 18 lists some common directory number features and their support based on the type of line mode defined with the ephone-dn command.

An octo-line directory number supports up to eight active calls, both incoming and outgoing, on a single button of a SCCP phone. Unlike a dual-line directory number, which is shared exclusively among phones (after a call is answered, that phone owns both channels of the dual-line directory number), an octo-line directory number can split its channels among other phones that share the directory number. All phones are allowed to initiate or receive calls on the idle channels of the shared octo-line directory number.
Because octo-line directory numbers do not require a different ephone-dn for each active call, one octo-line directory number can handle multiple calls. Multiple incoming calls to an octo-line directory number ring simultaneously. After a phone answers a call, the ringing stops on that phone and the call-waiting tone plays for the other incoming calls. When phones share an octo-line directory number, incoming calls ring on phones without active calls and these phones can answer any of the ringing calls. Phones with an active call hear the call-waiting tone.

So for your example it might be;
ephone-dn 50 octo-line
number 100
ephone 10
button 1:60 2:50
ephone 11
button 1:x 2:50
Cheers!
