Can't delete cordless extension

[baniamb]

Hi,

we're using MX-One 5 SP5 and have strange issue. We're trying to remove cordless extension, but we can't. First I'm running

cxaki:dir=301

and it's running ok. But when after this I'm trying to run

extension -e -d 301;

I'm getting strange information:

Extension 301 is busy.

I've searched everywhere, all call lists, all key extensions, but there's no information about using this number. Where can be the problem?
