SDP header issue

Hi, I have problem. Although the caller makes an audio-only call, the callee receives this request as a video session such as in the following headers. As you see it has both m=audio and m=video. I tried to change videosupport=yes and then videosupport=always but it didn’t make a change. We tried it with different phones that don’t have camera on the callee side but no luck. We need this because we must offer the callee the option to answer audio and video. We use Asterisk version 11. Thanks.
