Calls get stuck in 'ringing'

When I dial from one extension to another, if I hang up before the receiving party answers, the call gets ‘stuck’ on the screen of the phone showing an incoming call is ringing. It doesn’t actually ring, just says ‘From xxxx’ with the ringing phone symbol.

I’m using RasPBX with 2 x Cisco 7911s on SIP11.8-5-3S.
