Maybe one should be able to configure this - on ressource basis.

If you have a dump PSTN-GW (commercial soft-switch) which is not able to
give you the information back, the LB have to control the load. On the
other hand, if you can get the information from asterisk, yate etc.pp.
the LB modul should use this information.
