Hi there, I got some interesting feedback with my previous topic, so I'm now asking for a last question : In my configuration we need to work with DECT phones everywhere. Indeed, I need to be sure that any people will be able to move around with their phones. Pb : Snom M9 phones only allows 9 phones to be connected on 1 base. And as we'll be at least 90 users on our main site, some 3CX "experts" told us that it's possible to use Aastra DECT/IP antennas, combined with Aastra 142d (or 610/620/630) phones. And this may work fine with 3CX, allowing us to use roaming and hand-over possibility, plus advanced functions such as centralized address book... Do you think that DECT/IP solution is reliable ??? As Aastra is propriatary brand, I'm not sure this will work. Thx per advance.
