I'm working with Murex and the weakness of the software for FX and equity exotics with smile is about the calibration engine which doesn't exist at all (except for interest rates exotics). I think NumeriX is partnering with Murex and you can get decent calibration procedures from NumeriX librairies, but you'll have to pay extra money for that. So if you're only getting the basic Murex, then your exotics guys are right not to trust Murex when dealing with vol smile or vol surfaces.
