#### Description <!-- Describe your changes in detail --> Alg 13 did try to distribute calls to inactive destinations. If the highest priority destination is inactive, hash is not updated and the xavp is not set. This is resulting in failover mechanism not working at all for the given call.

When the hash variable is not updated, it makes alg 13 behave like round robin if the scenario above occurs. If you got two destinations and the highest priority is out of service, 50% of the calls will fail.

Now I tried a more simple approach updating hash with the first entry of the sorted list.

Also fixed a typo in a variable name. You can view, comment on, or merge this pull request online at:
