Audio Fine, Video - no

Jan 17, 2012 3:06 PM



I'm trying to set up the latest FMG/FMS to work with our video conferencing/media server.  Basic setup is fine, flash phone connects and calls are intitated.  G711u audio is good.  Video, both at a VGA and CIF resolution doesn't make it through the gateway.  A wireshark trace tells me a vidfeo RTP stream (h.264) is arriving.  But, nothing on the flashphone.


Some pieces of the config are included here.  sip.xml:



                        <!-- Unique name for the profile. This ID is used in workflow to identify where the call will be placed -->

                        <profileID> sipVideoPhone </profileID>

                        <!-- SIP username -->

                        <userName> FMG </userName>

                        <!-- SIP password -->

                        <password> FMG </password>

                        <!-- SIP display Name, can be same as username -->

                        <displayName> FMG </displayName>

                        <!-- Here the client is binded dynamically, in which case the sip phone's ip address is bounded by the register request -->

                        <remoteSipHost> </remoteSipHost>

                        <!-- Global Address if the FMG server is on a local network and need to connect to outside network -->

                        <!--globalAddress> </globalAddress-->

                        <!-- Context in which incoming calls will be handled, this points to the context in workflow.xml -->

                        <context> sipPhoneContext </context>

                        <!-- supported Codecs for this SIP profile

                        If no codec is specified here then the codecs specified in CodecList would be used.

                        DTMF is always supported -->


                                <codecID> G711u </codecID>

                                <!-- Video quality level can be optionally selected for H264 codec

                                  using deviceId and qualityLevelId defined in videoqualitylevels.xml.-->

                                <codecID deviceId="GenericVtcDevice" qualityLevelId="cif"> H264 </codecID>





<Context name="rtmp">

        <!-- Diastar extensions -->

        <Condition variable="destNum" value="^400$">

                <AppNode sequence="1" app="bridge" args="sip|${destNum}@sipVideoPhone"/>

                <AppNode sequence="2" app="hangup" args="null"/>


        <Condition variable="destNum" value="^506$">

                <AppNode sequence="1" app="bridge" args="sip|${destNum}@sipVideoPhone"/>

                <AppNode sequence="2" app="hangup" args="null"/>





<device deviceid="GenericVtcDevice">

<!-- The following settings are included for reference and can be used with any device -->


<!-- Max-bitrate=1000kbps, profile-level-id 3.1 -->

<qualityLevel qualityLevelId="vga" fmtp="profile-level-id=42001f;max-br=1000"/>


<!-- Max-bitrate=385kbps, profile-level-id 1.3 -->

<qualityLevel qualityLevelId="cif" fmtp="profile-level-id=42000d;max-br=384"/>



Any help would be appreciated.
