you have the flexibility to set the transport to $du or $ru and then
relay. Or look at tm module, there are functions that can enforce a
specific transport layer. Solutions can be made in config, but the best
would be that the provider fixes it, otherwise you have to make a more
complex config file to figure out if you have to enforce the transport
manually or not, assuming you route calls to other endpoints that set
the proper transport value.
Cheers,
Daniel
