No Localization For Failover Gateway in Trunk

I noticed that localization is not used for failover gateways in trunks. Is there any way to get this to work? Without localization for the failover trunks, it’s impossible to use the second and third trunk. For example, I am sending 001133 as tech prefix to trunk A but can’t send the same to trunk B or C. Is this a bug or on purpose? Can it be modified or fixed?

I already answered in another post.
