Hi I am using Voipbuster with psjua, and calling 2 UAs works fine, but whenever I want to send an instant message, i get: "pjsua_im.h Failed to deliver message 'test': 400/Bad request" Am I guessing right that instant messenging seems not to be allowed with voipbuster, or did anybody got that to work?
