Description

There seem to be an 'issue' in RFC4733 regarding telephone-event and multiple clock rates (see also here), so some implementations put multiple telephone-events in its SDP when it offers codecs with various clock rates.

Unfortunately, for telephone-event format, currently PJMEDIA will only match the name, i.e: "telephone-event" and ignore the clock rate, so when answering SDP offer with multiple telephone-events, it will simply pick the first.
