Reproduce the call using two IMSDroid clients on the Android 2.2.3 emulator in Windows XP, connecting through the OpenVCS conference bridge. Compare the result with two Boghe clients, which reportedly provide speech, and determine why the clients connect without a speech path. Done when both IMSDroid clients can hear voice through the bridge.
