- 2. WHY PRAJHA TALK? • In most of the rural areas, people neither have smartphones nor they have access to internet. • In such areas, there are many individuals who have some one or the other gone abroad for study or work purpose. During the initial days student/person might not have international roaming number • Under such conditions they can contact their relatives successfully without the need of any Subscriber Identification Module. • This is also very helpful to the ones who are frequent travelers to different countries.
- 3. HOW IS IT POSSIBLE? • This is possible by integrating Google Cloud Platform with Twilio and 3CX. • It doesn’t matter if the receivers device is a conventional PSTN and whether the Caller has an active Subscriber Identification Module or a roaming number • The Caller must get an access to the internet which is freely available almost every part of the world.
- 4. TAKING A COOL SIP • SIP is an application layer protocol. It is a simple network signaling protocol for creating and terminating sessions with one or more participants. The SIP protocol is designed to be independent of the underlying transport protocol, so SIP applications can run on TCP, UDP, or other lower-layer networking protocols. • Typically, the SIP protocol is used for internet telephony and multimedia distribution between two or more endpoints. For example, one person can initiate a telephone call to another person using SIP, or someone may create a conference call with many participants.
- 5. TWILIO • Twilio is a cloud based service that enables powerful communication between mobile devices, applications, services, and systems throughout the business in order to bridge the gap between conventional communication. • Twilio allows software developers to programmatically make and receive phone calls, send and receive text messages, and perform other communication functions using its web service APIs. • Telephone infrastructure cab be hosted by Twilio through Google Cloud Platform (GCP) or other cloud services.
- 6. WHY ? • Twilio provides toll free numbers for call centers, support system through API based telephony • Twilio interconnects to the T1 ISPs to provide PSTN integration. Uses SIP origination and termination to originate and terminate calls on PSTN.
- 7. GOOGLE CLOUD PLATFORM • Google Cloud Platform’s specialty is providing a place for individuals and enterprises to build and run software, and it uses the web to connect to the users of that software. • Through GCP we get our public IP which will help us to connect our PBX from anywhere on Internet. In our case it is 35.221.10.239 or pratik.3cx.us(FQDN) Fully Qualified Domain Name. • To keep it up and running we are using the Cloud PBX and for that reason we are using Google Cloud Platform to keep the PBX posted on the cloud.
- 8. WHY 3CX IP PBX?
- 9. REASONS TO PREFER 3CX • Completed Software Based • Scales better • Run on existing Windows machine • Can also be Virtualize it to Hyper-V or Vmwre! • Backup PBX to disk- quick restore to another PC • More features, better integration • Saves Cost • Remote office extension calls are free • Leverage VoIP Providers such as Skype
- 10. BENEFITS OF 3CX Easy IP Phone Management • Automatic provisioning of IP Phones • Network wide updating of SIP phone firmware • Easy remote extension configuration Quick to install • Automatically configure IP Phones & Smartphones • Install 3CX in minutes • Web-based console • Easy to create new extensions • Configure rules quickly • Uses PUSH Technology to ‘wake up’ the

- 16. USE OF SIP IN OUR PROJECT • We are using SIP trunking in our project. • This mode of SIP is be used in PBX in order to connect to the internet. • Thus we have connected our PBX to the internet making use Session Initiation Protocol.
- 17. DIVING INTO THE SIP TRUNKING How does SIP trunking works? • Communications service providers make the use of SIP trunking in order to connect the SIP based PBX’s and UC systems to the PSTN. • SIP trunks make the use of the Internet Protocols to support multiple simultaneous call in line
- 21. DIVING INTO THE SIP TRUNKING Similarities of the SIP trunking and the VoIP • With the advent of VoIP came the IP PBX, which has now become the successor for premises-based phone systems. Similarly, SIP trunking has emerged as the successor to T1 for the trunking service to support enterprise telephony. • The other similarity is both are protocols, which define the standards for communications over IP networks. For SIP trunking, the acronym stands for session initiation protocol, and this standard applies to a wide range of communications applications beyond voice, including instant messaging and video. VoIP is more specific, where the Internet Protocol is concerned only with how voice is transmitted over IP networks.
- 22. DIVING INTO THE SIP TRUNKING Difference between the SIP trunking and the VoIP • SIP trunks are the physical connections that provide voice service to your phone system. PBX trunks only carry voice. They are expensive and inflexible, but very reliable. • VoIP can be routed over PBX trunks via a media gateway, but to take full advantage of VoIP's capabilities, businesses will deploy SIP trunks and typically route these calls via a session border controller
