I have configured an Asterisk machine, and usually it works OK. However, sometimes the users complain about their calls crosstalking (that is, they hear the conversation of other user in their calls). This happens from time to time, randomly.
I have to clarify that our system uses analog phones that are connected to Asterisk using a FXS gateway (so each phone is linked to the gateway using it’s own regular phone line cord, which due to the size of our office, are pretty long).
I have read a lot of cases about no sound in calls or one way audio, but crosstalking is something that seems pretty unusual in VoIP calls. Could it be related to some kind of Asterisk misconfiguration? Or it’s more likely that it has to do with other external factor, like the network, VoIP provider or the phone line cord?
