Alcatel Unleashed

Looking for a solution for a customer who has to broadcast twice.
User has a external tannoy connected to the OXO via the AFU card, working fine using broadcast prefix 41. There is also a second broadcast group for internal users, 42. Is there a way of creating one group for both internal users and the external tannoy working as one ?

Regards

In Broadcast group you can add subscriber with internal number LSPK and name Loudspeaker(s).

LSPK can only receive broadcast therefore if you put users who can receive internal or external you get a message stating it cant be done.
Therefore a receptionist has to tannoy twice, surely there must be a solution ?
