Sound not OK (Choppy Sound) while using ManagedSession (.NET/C#)
Hello, I have successfully entegrated a dll-module (written udner .Net / c#) in fs which is loadable by the mod_managed component. Now, if I try to stream a wav file to the callee then the sound is very poor and choppy (also the file is played slower). The fs is running under Windows XP and tested under Windows 2003 with the same result. Streaming by using FreeSWITCH.Native.Api() works without problems, sound is perfect. Samples which I have tried: 1 - This works fine but delegate mechanism is missing there: FreeSWITCH.Native.Api fsApi = new FreeSWITCH.Native.Api(); string uuid = fsApi.ExecuteString("create_uuid"); string apiResult = fsApi.Execute("originate", string.Format("{{ignore_early_media=false,absolute_codec_string='PCMU'}}[origination_uuid={0},origination_caller_id_number={1}]sofia/gateway/Test/{2} &&playback({3}", uuid, callerID, phoneNumber, wavFile)); 2 - ManagedSession is integrated but we have sound problems: FreeSWITCH.Native.Api fsApi = new FreeSWITCH.Native.Api(); string uuid = fsApi.ExecuteString("create_uuid"); string apiResult = fsApi.Execute("originate", string.Format("{{ignore_early_media=false,absolute_codec_string='PCMU'}}[origination_uuid={0},origination_caller_id_number={1}]sofia/gateway/Test/{2} &park", uuid, callerID, phoneNumber)); FreeSWITCH.Native.ManagedSession blegSession = new FreeSWITCH.Native.ManagedSession(uuid); if (blegSession.IsAvailable) { while (!blegSession.answered()) { blegSession.sleep(500, 1); } if (blegSession.Ready() && blegSession.mediaReady()) { //blegSession.Answer(); //blegSession.Execute("playback",wavFile); blegSession.StreamFile(wavFile, 0); } blegSession.Hangup("Normal call clearing"); } Is there a mistake in my code or do I have forgotten something? Can you support me with some examples? Another issue is, that I am not able to make a origination directly by ManagedSession or CoreSession without using the FreeSWITCH.Native.Api(). How can I create an instance of a CoreSession object? Many thanks for you help in advance. Ali
In example two you are parking the call. You are then playing media into a parked call. I am not sure this is valid. According to the wiki "Please note that to retrieve a call that has been "parked", you'll have to bridge<http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_bridge>to them or transfer the call to a valid location." - so you might need to transfer that parked call to a DialPlan App before you try and play media - or just not park it in the first place. I might be wrong - but that where I would start. On Wed, Jul 7, 2010 at 8:03 AM, Durmuş Ali Öztürk <ali.stgt@gmail.com>wrote:

When a call is parked you can send commands to it to do anything you want. /b On Jul 7, 2010, at 8:30 AM, Phillip Jones wrote:

instead of originate to park then sending the uuid to the constructor try supplying the dial string to the constructor which will place the call On Wed, Jul 7, 2010 at 8:30 AM, Phillip Jones <pjintheusa@gmail.com> wrote:
