We replaced our SPA3102 with a SPA232D. FXO port is connected to our analog line, Internet port is connected to our LAN. The PSTN line on the SPA232D is registered with our Asterisk server so calls go through our analog line. From our IP phones to outside, everything is OK. From outside to our IP phones, there is some problems when the call is ended : if we hang up before our external caller, the line remains open on the caller's phone. If the caller ends the call before us, we hear the disconnect tone and the calls end normally.
We tried some settings here and there but unsuccesfull... Could you help please?
