WCF - Consuming JSON parameters through a POST

Can anyone please help me determine why my wrapped JSON parameters are coming in NULL?

I'm trying to integrate a vendor's product into our internal software and have created a WCF web service to handle their POST requests.

The vendor's JSON data format in the request body look like this:
{ "Call": { "call_detail_id": "3514736", "ouid": "7425" } }

If I create a test interface with WebMessageBodyStyle.Bare and pass in a couple JSON parameters, it works great. However, the vendor's typed JSON is not coming through.

Any help would be very much appreciated.

Thanks,

[ServiceContract]
    public interface IMyService    
{
        [OperationContract]
        [WebInvoke(
               Method = "POST", 
               UriTemplate = "post-call/",
               RequestFormat = WebMessageFormat.Json, 
               ResponseFormat = WebMessageFormat.Json,
               BodyStyle = WebMessageBodyStyle.WrappedRequest
               )
        ]
        string lmc_BusinessLogic(Call myCall);

    }


    public class Call
    {
        [DataMember(Name = "call_detail_id")]
        public string call_detail_id { get; set; }
        [DataMember(Name = "ouid")]
        public string ouid { get; set; }

    }

Implementation:

public string lmc_BusinessLogic(Call myCall)
        {
            // myCall object is null when passed in here.
            // Implement some business logic once the parms are getting passed.

        }
