Alcatel Unleashed

Hi all,
I need a configuration to working like twin sets ( or similar) between one IpTouch 4038 and one analogic station.
The idea is that the user can retrieve the call from any of both sets, and publishing one only Directory number.
We can't configure twin sets or Multiline secondary key.
Any suggest will be appreciate.
Regards,
M

Set supervision with off hook configured on IP touch. (inbound scenario)
Routing at off hook on IP touch with dialing table using substitution with analog number. (outbound scenario for ip touch)
Analog set number will be the main number.
