Ringgroups Module make answered elsewhere, shows no missed calls when nobody answers.

When updating the ringroups module from 15.0.11.10 to 15.0.11.11, when a call comes in through a ringgroup that has "mark call answered elsewhere" set to Yes.  After the update to 11.11, when a call is received, and nobody answers the call so it goes to coverage, no phones show a missed call. 

I rolled back to 11.10, and everything is working fine, so something was changed in 11.11 that breaks this function.  We are using an assortment of Yealink and Aastra phones, and 11.11 breaks.  I have rolled back to 11.10 for now, but wanted to report this..
