Cannot see the parked calls context in my internal context

Hi,
I am trying to get call parking to work, but I cannot seem to get my internal context to see the parkedcalls context. Put it like this, when I dial 701 to re-connect with a parked call, it drops out of the bottom, and goes and rings out on my zap circuit, onto analogue BT lines.

Now when I transfer to 700, asterisk tells me that it has placed the call at number 701, I then dial it, and end up confusing that nice sounding old lady at the BT exchange.

I am running 1.2.18.

Any offers?

Cheers,

Rob.
