Here is an example.
All PBX are in a cluster with Ip Trunks
PBX A MXEIII rls 6.0
PBX B MXeServer rls 6.0
Nupoint connect to PBX B
Someone call PBX A on a PRI Trunk. (1234)
1234 is a speedial to Nupoint (Call FLow) connect to PBX B
Customer chose an option that will send him to an Acd Path to PBX A
The Agent ID that will take the call on an IP Phone is in PBX B.
When the call is establish, what is the path? Is the path a---b are a---b----a----b

Route optimization is designed to take care of multiple call paths between sites for single calls.
For the record, the most likely scenario for tromboning occurs with 3 sites.
Site A has redundant routes setup to get to site B. Either Directly or, redundantly via Site C.
Site C has redundant routes setup to get to site B. Either Directly or, redundantly via Site A.
Scenario:
Site B has an issue and can no longer be contacted By either site A or C
A call initiates from A to B but cannot succeed directly so call proceeds via Site C
Site C tries to send call to B but cannot succeed so call proceeds via Site A
In seconds, the entire path between site A and Site C is saturated with 1 call consuming all paths.

What's most important is that you realise ... There is no spoon.
