IPO 2 SIP Phones 1 Extn IPO 2 SIP Phones 1 Extn Ala99 (TechnicalUser) (OP) 20 Sep 21 21:24 Hi All, I need to set up two phones (SIP Extn H2xx) to share one extension incoming and outgoing, How do I set this up? is there any way to register one extension on 2 phones ? It's IPO 11 Thanks, RE: IPO 2 SIP Phones 1 Extn tac84 (Programmer) 21 Sep 21 09:44 One way you could do it is have both phones have their own extension and the one you want to share, you create a user for then use MADN appearances which work similar to Bridged. Any external number can have an ICR record set to the "Phantom" or "Shared" extension number, then both phones have appearances for the Shared extension, along with their own respective call appearance keys. I would use MADN Single and make one for each appearance (eg. a, b, c). MADN multiple could be a bit more confusing for the users. MADN is a great feature of R11.

Internal twinning even shows the main extension number as caller ID for internal calls but can no longer be called directly which sometimes confuses people.
