[SR-Users] Parallel call forward

[Raúl Alexis Betancor Santana]

I did not use the index to erase pull from the stack I directly set it to null 

$(avp(s:cf_destinations)[0]) = $null; 

If I do this: 

$var(new_ru) = $(avp(s:cf_destinations)[0]); 
... 
append_branch($var(new_ru)); 
... 

I got the same result ... just the LAST $ru I set is the one thats called.
