If you make a call between an IP phone and the PSTN and hang up on the PSTN first, does the IP phone hear anything?

If a pstn caller makes a call and attended by the ip phone then disconnect by pstn ,it is working fine

But pstn caller disconnects before attending by an ipphone,then there is pblm with fxo port

One more thing : some of the calls are not attending by the router(there is a ring detection and suddenly disconnects)
