Could this perhaps be because the phone doesn't support "bypass" or re-INVITEs? Is there a way to disable this functionality and instruct asterisk to just stay in the middle of the conversation (bridging or native-bridging) for the duration of the call? I thought that setting directmedia=no and directrtpsetup=no would disable re-INVITEs and force asterisk to use bridging mode, but perhaps something else is required?
