<p>There is a bogus character 0x01 sent after U command when calling rtpproxy_engage("").<br>
If calling rtpproxy_engage(), everything seems to be normal (please note the missing double quote).</p>
<p>rtpproxy output log:<br><code><br>
DBUG:get_command: received command "6197_17 U#001c0,107,8,101 LYTy2eZwa8DCiwQ.XwUB5RAyuvXqxK0T XXX.XX.XXX.XXX 4010 K2HuCGCbGY-3pdBhz9EUBt.XAJH0yblY;1"<br>
