Running jssip 3.9.1.

Freepbx has a feature where it can send a prompt over early media and expects a password sent back over DTMF, before the call is answered.

When I try to respond to the prompt with session.sendDTMF(), it throws an INVALID_STATE_ERROR: Invalid status: 2.

Is there something additional I need to do to the session to enable sending dtmf over early media, or is this a JSSip limitation?

Thanks,
Matt
