Cannot add a station, server was dismounted

[AlekseiRUS42]

Hello everyone!
Before September 2021 we had 2 servers s8500 in 2 different locations (let it will be server1 and server2). There was station 55900 on server2. Then we make an optimisation and switched off and dismount server2. G650 of server2 was joined to server1 via net as other port-network. Now I'm trying to add station 55900 to a server1, but got message ""55900" identifier previously assigned; please select another"

I tried several next commands (no success):
list usage ext 55900;
list usage digit-string 55900;
add vdn 55900 (read this one in one of tips);

I've heard that the only resolution for me is reset system 4. Is it right? If so, this method have 100% of success? There is a little difficulties for resetting system.

P.S. We didn't do a remove stations (inc 55900) on server2 before dismount.
P.S.S. Maintaining back server2 and remove a station is impossible variant.

Thanks to AvayaTier3. Command "list extension-type" helped and 55900 was there as remote-access. Idk what is it. We've never doing this and station 55900 worked normally until sep-2021. Anyway thanks for support! Problem solved.

I think remote access is the new name for DISA, personally I think it is a security risk but they want to use it at our place.
