[SR-Users] Parallel call forward

[Daniel-Constantin Mierla]

Hello,

you should not use index when setting an avp to null -- remove the [0].

Then you can print details of branches voa $branch(...) variable to see
what are the results of your operations.

A branch can be added also by providing the uri as parameter for
append_branch() -- see the documentation of the function in the corex
module.

Cheers,
Daniel
