[Serusers] rpid and append_hf

[Iqbal]

Hi

I have added rpid for each username in my DB and they are being picked 
up fine

 save_rpid(): rpid value is '123456789'
 4(2890) authorize(): set string AVP 'rpid = 123456789'

but when a call is made this is not being sent as the CLI, in fact I 
dont get a callerid.

I added append_hf to my routing block, after authorising, and after the 
correct gateway had been looked up, but alas no luck, anyone have a 
sample CLI route.
