One touch parking will not work on timeout

Hello,

We had a problem where if a parked call returns back to the parker, the parker will not be able to park it again using one touch parking. Sifting through the code, I found out that the return is done by "Dial"ing back to the parker with hard-coded channel option “t”. This will obviously not allow the called party to use one touch parking. Changing the option string to “kt” solved the issue. I’m not sure if this is a bug or an overlook since 1.2 (where “k” was not needed) or by design. I have a patch against 1.4.20-rc1, if any one is interested.[/code]
