Does anyone else have problems with MWI on analog phones using the ASU IIs?

It looks like the voltage being put out is too low.
 
Haven't heard of issues with the MWI voltage, but I've run across some other devices (loud bells and elevator phones in particular) that won't work with the lower ring voltage put out by the ONS ports. Fortunately in my case we have Per nodes as well and just run them off a Per ONS card, which puts out the full 90VAC that these devices are looking for.
 
Hmmm. Curious if the ringer current is sufficient to drive a Wheelock relay ????
