> On i2004 series nortel phones using chan_unistim with multiple lines, when receiving a call on a second line with a softkey appearance original call cannot be hung up on properly. Hitting the goodbye key or placing phone on handset indicates that call has been disconnected but phone call is still active, other party can still hear audio (which can be a very embarrassing situation). Phone often crashes after this. Tracked issue down to unistim_hangup function -- when hanging up the ringing line, driver doesn't restore the phone's original state if on another line. Attached patch fixes, although overrides some sort of DND icon display that forces icon statuses.
