The gateways can be used to provide toll bypass over an IP WAN (see 

). The call routing in this case is 

provided by the PBX systems. A call routed to the FXS gateway can be relayed on a port-to-port basis to the 
remote gateway or on a dialled number basis.

With the use of FXS ports extension dialing on the secondary side must be 
done through two stage dialling (DTMF relay).
