I have a user with a 5340e phone who uses the speaker key to answer calls frequently. Recently, it stopped working for outside callers. When an outside caller rings in, he hits the speaker key but just gets a dialtone. Pressing the speaker key again turns off the speaker and dialtone, and the ringing of the incoming outside call continues. For internal calling, the speaker key answers the call and puts it on speakerphone like it's supposed to.
Any thoughts as to what could change the behavior of the speaker key? I can't find a setting for it anywhere.
Many thanks!!
