Linksys PAP2 & Voipcheap Dial Plans?

Hi there,

I've been fiddling about with my PAP2 and creating some dial plans for use with Voipcheap.
My complete dial plan line is:
(<:00441578>[7]xxxxx|<:0044>1[2-9]xxxxxxxx|<:0>01[2-9]xxxxxxxxx|<:0044>8[4]xxxxxxxx)

To break this down to be understood (hopefully!)

I've now got it configured for local calls as:
(<:00441578>[7]xxxxx
Which works perfectly in the "01578" area code.

|<:0044>1[2-9]xxxxxxxx
For most "National" calls that I've tried this works fine so far.

|<:0>01[2-9]xxxxxxxxx
This works for calling the USA

|<:0044>8[4]xxxxxxxx)
Now this was my attempt at making a dial plan for "0845" numbers but I'm getting the tone that tells me it's not correct.
I need to create a plan for 0845 & 0870 numbers (which are a great way to use Voipcheap credits up!)
