T41P: Call Park Problem

The phone is simply too fast closing the connection after sending the call park code.
Like I mentioned above my PBX returns a positive feedback tone after about a second or so and than hangs up, when I park a call by pressing "Transfer" and enter the park code manually.
If I go the manual way and hang up before my PBX returns the feedback tone I get exactly the same behaviour when I use the predefined park button.

So the question at hand is: Is there a possibility (like adding a character to the call park code) to make the phone not to hang up or at least to delay the hang up, so the PBX has time to do what it has to do to park the call?

Dear User,
Thanks for your detailed discription.
I tried the same operation here on my T41P however I didn't experience this problem.
Regarding this issue, would you please reproduce this issue(park the call by pressing the park button) and then send us the config.bin file, pcap trace file and syslog on level 6 so I can look into it?
Please refer this FAQ on how to get these files.
