Matijs,

have a look at the "bool disc" parameter used in your call to UserInitialize. Should be true to avoid your problem I think:

When disc is set to true, calls to phones of the monitored user are cleared only after the user hangs up the phone. This way it can be avoided that the SOAP application assumes the phone is free but is still off-hook. This only works with innovaphone H.323 endpoints
