900MHZ SpectraLink decoding

Does any know if it's possible to decode spectralink? It's a commonly used system in many businesses from grocery stores to large factories.

we had that system in use at my hospital until last year. It is spread spectrum wideband- uses a crude 40 bit encryption algorithm IIRC. It was installed in the late 1990's. Decoding it would mean finding out the what spread spectrum chipset is used, and then cracking the encryption.

It was phased out in favor of SIP based DECT (we now use Ascom DH-4 series) and the SpectraLink system was taken out of service. I think of it as the Smartnet II of the wireless phone industry, they were workhorses- but if you've ever seen the racks of line cards needed to drive them, they are as fun to maintain as a CEB on an old Smartnet system. Like Smartnet trunking, lots of them still in use, and newer Spectralink systems use DECT, WiFi and I think they still support 900MHz, but most of the newer system are SIP based.

the new Ascom system also has better coverage, fewer base stations are needed, they have more capacity- and they play much nicer with other wireless stuff we have in use (telemetry on ISM 900/2.4, WiFi on 2.4/5.8, 800MHz trunking, Bluetooth...you know, just about EVERYTHING wireless in a modern health care setting!), battery life is much better, the handsets sound better and seem to hold up well (except for the stupid Nokia 5100-like connector on the bottom).

Ok, I don't have the technical knowledge to figure it out on my own but was just hoping there was a DSD style program out there. Thanks anyway.
