Here are the links to previously published guides that go into more depth on the topic. **SIP TRUNK**[Part 1](https://www.simpletech.uy/en/post/troncal-sip-empresarial-gu%C3%ADa-completa-parte-1/) **,**[Part 2](https://www.simpletech.uy/en/post/su-infraestructura-actual-es-adecuada-para-implementar-un-troncal-sip-gu%C3%ADa-completa-parte-2/) **and**[Part 3.](https://www.simpletech.uy/en/post/troncal-sip-antel-uruguay-parte-3/) One of the most obvious benefits and requirements when moving to SIP is that you must have an IP PBX installed in your company. This is the ideal time to rethink how to proceed from now on. We know that the decision to change your company's Telephone System is essential due to the impact it has on the entire organization and the responsibility it entails. That's why we created this new guide with the most important reasons for migration, comparing Legacy systems with 3CX, an Open Standard platform. We detail these six points on why we believe this change is so convenient for companies. **1.** **Functionalities provided by the system.** **2.** **Costs.** **3.** **Flexibility and autonomy in its administration.** **4.** **Audio and video quality and clarity.** **5.** **Security.** **6.** **Industry trends.** **1.** **Functionalities, present and future** First of all, we are convinced that expanding the communication capabilities of the company should be a priority. In this respect, 3CX exceeds the performance expectations expected from a telephony, contact center and unified communications solution. - **Unlimited interns**, without having to pay extra for mobility, call-center or other services. - **Mobility for all users**, thanks to the free 3CX application that allows the company's internal to work in a**remote**on Windows, MAC, Android and iOS from where you can control calls, manage contacts and see the presence status of other users. - System of **Integrated video conferencing**, 100 simultaneous participants. - **Call recording** per user, group or on demand. - **Integrated Call Center** with capacity**unlimited** of agents at no extra cost. - **Wallboard** for real-time analysis and monitoring of the performance of your agents. - Integrated voice application designer for the development of **IVRs** in an agile way for self-queries or self-management of users or callers. - Generation of **automatic reports** to have detailed information on user usage. - Fax server with PDF forwarding by email. - Integration with Systems such as CRM, ERP and other business tools such as: Microsoft Dynamics 365, Salesforce, Vtiger, Zendesk, Zoho, Microsoft Office 365, Freshdesk 1C, AmoCRM, Freshsales, Bitrix24, ConnectWise, Datev, EveryoneAPI, MS SQL Server, MySQL, PostgreSQL, MongoDB, Microsoft Outlook (Plugin), MS Exchange (Plugin), Nutshell, among others*. **Simpletech can integrate or provide you with the knowledge to integrate any other tool through the 3CX API.* **2.** **Costs, Open Standard platform** Opting for traditional platforms that limit our use of devices means risking being tied to an obsolete investment shortly after it has been made. 3CX is [Open Standard](https://www.3cx.es/voip-sip/sip-faq/) which allows the use of **any SIP device** on the market, not limiting you to having to use equipment from a specific brand. It also supports the WebRTC protocol, promoted by Google, which is representing the most disruptive movement in unified communications systems in the last 20 years. **3.** **Flexibility and Autonomy, 100% Software** With other brands, every upgrade for bug fixes and new features is usually paid for, has to be implemented only by senior engineers from the brand itself, and there is usually no graphical interface for the customer. Not even for small daily changes, such as creating a new extension, managing a voicemail, changing system voices, or the IVR etc. In contrast, 3CX provides a management console, its user experience is simple and intuitive. Being a software-based product it allows **unlimited flexibility** compared to the rest of the brands in this comparison. It supports being installed**On Premise** on any physical or virtual machine with minimal hardware requirements, and can be installed on both Windows and Debian Linux. It also offers the option of installation **Cloud**, hosted in our own Data Center. This differentiator allows us to choose the server of our preference without having to be tied to a specific hardware provider, unlike proprietary solutions that require a specific part that only the manufacturer provides. We are facing a paradigm shift in terms of UC systems, where the service becomes one more part of the company, just like email or CRM/ERP, and for which a proprietary “box” no longer makes any sense. **4.** **Audio and video quality and clarity** 3CX has Infrastructure of **globally distributed servers**. Which helps us ensure better call routes and offer more robust connections. Top quality calls with guaranteed latency and minimal jitter. When evaluating call quality, the **latency and jitter**are the main factors that affect the ability to be heard correctly, without distortion. We calculate latency as the round-trip time to send and receive packets. Regarding the latency and Jitter of our Cloud services: We are located in Antel's Tier 3 Data Center with average latency levels of 10ms for all of Uruguay and 20ms in the rest of the LATAM region. The Jitter values recorded at various points in LATAM were 5 milliseconds for Uruguay and 10ms for the region. **5.** **Security** This includes tunneling (type of VPN for remote extensions/offices), automatic banning of IPs that fail to enter the system access password more than 3 times, predefined high security passwords, access limitation by IP, limitation of destination of outgoing calls, etc. Integrated SBC, automatic backups, failover (backup server for fault tolerance), high availability, backup and restore in minutes, downloadable updates. The economic group to which 3CX belongs owns [Acunetix](https://www.acunetix.com/vulnerability-scanner/customers/) which is a company specialized in web security and whose clients include the US government, CHINA, VISA, among others. **6.** **Tendencies** At the product level, 3CX set out to be faithful to its philosophy and follow the trend of providing **freedom of choice for its customers**. This is demonstrated by two key features: the first, as it is a software-based solution, provides complete freedom in the decision for the installation of your server and the second, the freedom to choose VoIP equipment as it is compatible with open standards. On the other hand, the virtualization of systems has been an established trend for some years now, and the benefits of taking them to cloud scenarios, in order to be able to use the platform with own devices (BYOD) such as PCs, cell phones or tablets are so evident that they have made them grow widely. 3CX grows at a rate of **40% annual** and is the most solvent professional UC platform with the greatest growth potential on the market at this time. It has been selected by more than **250 thousand leading companies worldwide**. While other big brands suffer with the tremendous reconversion necessary and have to declare themselves in **bankruptcy as in the case of Avaya in the USA or mergers such as that of Shoretel by Mitel must take place** because the results they produce are not good. _____________________________________ In search of **advice**to hire a SIP Trunk for your company?
