Looks like Western Rivers recently sold to some sort of conglomerate.

HME (Hunting Made Easy) or something like that. They have a ton of different brands under that name. But the Western Rivers electronic callers have a new look and new names. Looks like a combination of ICOTECH and FOXPRO packaging...?

Feel bad for the older style owners as it looks like they also took down their sound file and support web page.
