По-моему, это очень сильное колдунство - заменить

StringBuilder sb = new StringBuilder("{");

foreach (var company in AvailableCompanies)

{

sb.AppendFormat("\"{0}\":[{1}],", company.CompanyGUID,

string.Join(",",

AvailableCalls.Where(call => call.CompanyGUID.Equals(company.CompanyGUID)).ToArray()

.Select(c=>string.Format("\"{0}\"", c.CallGUID))));

}

sb.Remove(sb.Length - 1, 1);

sb.Append("}");

return sb.ToString();

на

return Memo.User.Calls.GroupBy(call => call.CompanyGUID)
.ToDictionary(group => group.Key.Value.ToString(),
group => new JsonArray(group.Select(call => new JsonPrimitive(call.CallGUID.ToString()))))
.AsEnumerable()
.ToString();
