 Ladies and gentlemen, good afternoon. Thank you very much. You're staying here to attend the session. I know that after three days long, four-day presentation, everybody exhausted is kind of the torture. And thank you. Give me a chance to torture you. Thank you. So my topic is building communication apps on OpenStack Cloud architecture. My name is Liang Li. I'm from TeleStacks. ResCom, we are talking about ResCom. ResCom is an open source project based on MobileSense, which has grown over the last 10 years. And now MobileSense is readily deployed as a software, as a service. ResCom supplies a rest for API access to powerful capability and communication capability of the communication platform. So web developers can build the communication application through the rest for API. And without leaving their comfortable programming environment, for example, PHP, Java, Python, .NET, Ruby. And MobileSense is a most popular telecom open source community, which has been contributed by many industry key players, including Huawei, Avaya, Cisco, Tulio, Orange, Red Hat. And based on MobileSense, TeleStacks supply a full portfolio of communication platform to facilitate building the value add service application. From this chart, we can see that TeleStacks communication platform, including a lot of components, including media server, JinSleece container, CIP server-led container, USSD Gateway, short message center, data meter, et cetera. Above all of the components is ResCom. Now let's talk about ResCom. ResCom is a real-time cloud communication platform for web developers to build and skill voice web RTC, voice fax, video, and the message apps for web RTC, CIP, and the PST networks. You can deploy your own Tilo or Tropor in a box in no time. ResCom supply a telecom API, network API, to web developers, which is very easy to use. And the API is totally compatible with Tilo API. So it's very easy for web developers to integrate the communication capability into their application. The communication features is provided by the MobileSense platform. And ResCom can be very easy deployed in public, private, and hybrid cloud environment. Actually, we have launched the AMI, ResCom AMI, on the AMOZOMax place. You can try it out very easily and quickly. For private cloud, we have the success story deploying the ResCom on the open stack. We can talk it later. And also, the ResCom features a plug-up for architecture. You can choose SP service provider of your choice. Use the service provider of your choice to send a sort message, convert VYP to legacy, and use your text to speech vendors. This is a screenshot of ResCom VYP innovation for web recognition on the marketplace of the AMOZOM. We know that developing application in telecom world is a very hard job. It's challenging. We must have the developer who dedicated to expertise, who understands the low-end protocol. For example, SMPP, USSD, SAP, RTB. But web developers has been accustomed to simplicity. So ResCom is a bridge between the two worlds. Through the ResCom, the web developers can build the communication capability into the web application very easily. They can just call the ResCom and command the ResCom to handle the complexity of the telecom. Of course, the telecom operator also can leverage the ResCom as a platform to build the value-added service quickly and efficiently. OK, we see some examples. If your application wants to send a short message to a number, and it can just make a very simple XML call to the ResCom, and the ResCom will handle the SMPP protocol or MAP protocol to deliver the short message. This example of XML, we can see it's pretty easy. You just use the SMS tag to command the ResCom to send the short message. And if there is an incoming call to the ResCom platform, for that incoming call, for the given number, the ResCom will ask your application how to handle that call. And the application can easily use the very simple XML to command the ResCom, put the call. ResCom put the call into the conference. We can see this is an example of how to handle this call. First, the application use the C tag to greeting the callers, and then use the dial and the conference to put the call into the conference. OK, we can see some ResCom features and use keys. First, you can use ResCom to handle the outbounding call. For example, create a predictive dialer, do the appointment reminder, click to call, call queuing for call center application. Also, you can build the IVR very easy. You can design the main phone manual call center, use text to speech to greeting the caller, and also prerecorded the fails. And also, you can build your own conference system on a fly. You can play on hold music. You can record a conference. You can beef on exit of a participant. It's all on java.php.net to call the ResCom to do it. And also, you can record the voice. We have the media server to help to record the entire call for later use. We can promote user to leave a voicemail. We can get the record fail whenever you want, or you're recording on specific DTMF recognition. For short message USD email, you can use ResCom to do the appointment reminder, deliver a follow-up, force, marketing campaign, grouping messaging. Of course, you can design UI, self-ported UI for users easy to configuration. Subscribers can manage their short message, voice recording, call logic, or something like that from UI. And also, we have the web artistic capability. You can realize the browser to browser to PST audio call. You can do the browser to browser video call. The screenshot on the screen, you can see that we can four people to hold a video call through the web RTC. Now we can see a success story of how they leverage the ResCom. Heresense is a US company. They enable caregivers to provide the right care at the right time in the preferred environment. The main target of them is improving observations through remote monitoring combined with analytics and accelerator action based on early improved observation and travel better outcome, reduced cost, and improved care. Heresense is a innovation leader in technology-enabled care solution. They are funded in 2001. They have 116 clients and a care room for more than 12,000 individuals. They recognize the market leader in technology-enabled care, combine real-time data with powerful analytics and a multi-modal communication. Heresense's technology solution is delivered through Heresense Advantage. It's a private cloud based on OpenStack. From this chart, we can see the people from their home or living apartment can send the data to the OpenStack platform. Of course, the data including the voice, the sensor data, and other things. And on the OpenStack, we deployed the ResCom solution, including the ResCom, including the CIP container, including the media server. And the OpenStack connect to the telecom operator through the CIP trunking. Let's see a scenario of Heresense Advantage. An alert based on a specific event. For example, Molly is an aged lady, already 74 years, lived in Illinois. And he has a history of dizzy spell. And Heresense installs sensors into Molly's home because he is far away from his parents. And they use Heresense technology to monitor his health. And in the morning, Molly get out of bed in the morning. And the neighborhood motion sensors detect the initial motion. Then no motion in apartment. And this alert is observed by Heresense Advantage and triggers the ResCom to have an alert call, send it to care staff at other place. And then they help Molly to her fate. Molly avoid hospitalization, loss of independence. And also Molly increased in toilet activity, perhaps two times normal use. And in the neighborhood, the toilet sensors monitor activity. And analytics identity is a problem. And then alert email by ResCom to caregivers with relevant data. And the care team then diagnosis early stage and can give him red treatment. Also, you can use Heresense also can do the automatic residence check-in, automatic phone question for disease management of chronic conditions. For example, the system can call four times every day to the older people. And let them to tell their environment by pushing the keyboard over the phone. Are you OK? Are you first comfortable? You can please one or two. And based on input, and as a doctor or the caregivers can call back to the age people to find the mode situation. And also the alert communication can be routed based on customized ResCom based call tree. You can design different call trees and use a different policy at different times based on different situation of the ages. OK? Now let's take a look, key study, key takeaway. Now we live in the API world and the economy. So we no need to reinvent the wheel. Just export your network assets today to the world like the telecom operator, the PST network, or internally for your team. So others can leverage your capability of the network easily. Also partner today and drive new source of revenue. Last but not the least, I will make a small adjustment. Between the 21st to 22nd in Bangkok, there will be a telecom application developed someday. And it's supported by Huawei, Ubuntu, OpenCloud, and the hope to get the telecom developers stay together to talk about the innovation of the telecom in the future. So this is our website. If you have any question, you can send me an email or access our website to get more information. Thank you very much for your time. OK.
