Sure Let's take a couple of examples:
The easiest is a class 4 replacement. I have trunk gateways connected on an ATM network, with a "softswitch" running MGCP or, more likely, Megaco. I can use SIP between Softswitches, or I can use something like Q.BICC. Another case is when I have a SIP end device on an ATM network. There are some very interesting uses for such networks where reliability under "surge" conditions is required. I could also have a SIP end device that was Ethernet attached on a LAN, interworked to an ATM core through a gateway to a WAN, using switched virtual circuits across the WAN.
