[asterisk-users] Why do Zaptel calls drop all of a sudden? Couldbusy detect be the problem?

[Martin]

Well for the best test you can call in on that line and fire Echo()
app and then you'll see if the lines
"hangup by themselves" ... is you use fxsks/fxs_ks signaling and it's
supported by your lines
then it's that that makes remote hangup possible
