Modify Originate input syntax

This adds the | to the originate syntax 
making it possible to put a list of urls to call and attempt
to call them one at a time until one of them is successful or there
are none of them left

The original & delimited list is valid for each step in the | separated
list

Example
sofia/test-int/3920@10.3.3.104|sofia/test-int/3910@10.3.3.104&sofia/test-int/3920@10.3.3.104

first call 1 location and if that results in a failure, try 2 at once on the next go
