TAPI - Unpark call issue

[n1k05]

Hello,
i'm having an ip500 system and a win XP pc with TAPI drivers
installed. I'm also using julmar's TAPI soft phone (

http://www.julmar.com/tapi/)

to handle an extension. Call park is ok, but when i unpark call i don't get any call info like call state, caller id, called id and other, although i have call info on my hardphone. The same issue is happening and with other TAPI softphones.
The system has a CTI Link Pro license and i'm using the latest TAPI drivers.
Has anyone dealt with a familiar problem?

I would guess that you would need to invoke the unpack command twice. As with the handset pressing unpack the first time gives you the call information, 2nd time picks up the call. Think this was introduced late v5 or v6
