Frequently Asked Questions
( FAQ )
General Questions
What is SIP Trunk and how does it work?
SIP Trunk, or SIP Trunking, is an IP telephony technology that enables phone calls over an IP network, such as the Internet, without the need for physical links like E1 or R2. It works as a virtual channel that connects your phone system (IP or Virtual PBX) to the public landline telephone network (STFC). With it, you can make and receive multiple simultaneous calls, with high-definition audio, without cables or boards, and with unmatched flexibility. It is the modern replacement for the traditional telephony link, ideal for companies seeking quality, savings, and scalability.
What is the difference between SIP Trunk and standard VoIP?
Although both use IP to transmit voice, SIP Trunk is a more robust business solution, with simultaneous channels, failover, optimized codecs, and integration with professional PBX systems. Standard VoIP is more geared toward residential use or small operations, without control of simultaneous calls, without redundancy, and with lower quality. SIP Trunk is a professional, secure Telephony Link compatible with corporate environments, with an SLA and real technical support.
Does SIP Trunk replace a conventional phone line?
Yes, SIP Trunk replaces conventional phone lines with clear advantages. By using SIP Trunking, your company gains the ability to make and receive calls with more simultaneous channels, more competitive rates, and integration with digital tools. It is the natural evolution of business landline telephony, with better performance, lower cost, and centralized cloud management.
Does SIP Trunk work with standard internet?
Yes, provided your internet connection is stable. To ensure the best performance of SIP Trunk as a business Telephony Link, the use of business-grade internet links is recommended. VulcaNet can also recommend partner ISPs with optimized routes to ensure HD voice and secure connections.
How many channels can I have on a SIP Trunk?
The number of channels on a SIP Trunk depends on your needs. Each channel represents one simultaneous call. You can subscribe to anywhere from 1 to hundreds of channels, with full scalability as your demand grows. SIP Trunk is more economical than E1 links, where you pay for fixed blocks of 30 channels even when you do not use them.
Do I need a PBX to use SIP Trunk?
Yes. SIP Trunk is designed to connect to a phone system (IP PBX or Virtual PBX). It does not replace the PBX; it is the channel that carries calls between the outside world and your internal structure. If you do not have a PBX, VulcaNet offers complete solutions such as cloud PBX already integrated with SIP Trunk.
Is VulcaNet SIP Trunk approved by Anatel?
Yes. VulcaNet is a Landline Telephony Carrier (STFC), authorized by Anatel. This means your SIP Trunk follows all legal telecommunications standards in Brazil, with valid numbering, guaranteed portability, and legalized operation. Unlike unregulated VoIP solutions, our infrastructure has certifications, contracts, and responsible technical support.
Benefits and Use Cases
What are the main benefits of SIP Trunk?
With VulcaNet SIP Trunk, your company gains several benefits: savings on telephony, on-demand scalability, superior voice quality (HD), integration with service systems (IVR, CRM, Chatbots), cloud activation, number portability, engineer-led technical support, and nationwide coverage. All of this makes SIP Trunk a modern, strategic Telephony Link for any operation.
Can I use SIP Trunk in all branches of my company?
Yes. One of the greatest advantages of SIP Trunk is telephony centralization. With it, all your units can share the same trunk, optimizing costs and management. You can distribute channels across headquarters and branches intelligently, with a continuity plan and unified cloud monitoring.
Does SIP Trunk help reduce operating costs?
Absolutely. SIP Trunk replaces multiple analog or digital lines (E1/R2), allowing you to pay only for the simultaneous channels you use. It also eliminates expenses with physical infrastructure, installation, boards, and technical visits. VulcaNet also offers competitive rates for local calls, DDD, 0800, and free portability, ensuring the best cost-benefit.
Is SIP Trunk secure for my company?
Yes. VulcaNet operates with modern security protocols, encryption, SBCs (Session Border Controllers), two-factor authentication, redundant routers, and real-time monitoring. In addition, we follow practices based on ISO 27001 and ITIL v4 standards. Your communications are handled with the same technical rigor required by banks and large corporations.
Is it possible to integrate SIP Trunk with Microsoft Teams?
Yes, VulcaNet offers integration with Microsoft Teams via Direct Routing. This allows your team to use Teams as a phone system, making and receiving external calls with your corporate numbers. The solution is ideal for companies that want to unify internal and external communications on a single platform.
Can SIP Trunk be used with voice bots and IVR?
Yes. VulcaNet SIP Trunk is compatible with voice bots, IVRs, APIs, and chatbots. This allows you to automate customer service, reduce operator costs, and improve the customer experience. It can be integrated with CRMs, ERPs, WhatsApp, email, and other channels, creating a true omnichannel communications ecosystem.
Installation and Support
How is SIP Trunk installed?
Activation is 100% cloud-based. After subscription, our technical team provides the SIP connection details (username, password, IP, port, and approved codecs). If you have an IP PBX or Softswitch, configuration takes minutes. There is no need for cables, boards, or an on-site technical visit. Everything is done remotely, with support included.
How long does it take to activate SIP Trunk?
VulcaNet SIP Trunk activation is among the fastest in Brazil. On average, it takes from 30 minutes to 24 hours after contract validation. We have automated provisioning and portability processes that speed up the entire journey.
Who configures my PBX with the SIP Trunk?
If you already have an IT team or PBX provider, you can use our technical instructions to perform the integration. If you need support, we offer onboarding, remote configuration, and certification consulting. We work with the leading integrators in Brazil and provide technical support to ensure everything works from the start.
Does VulcaNet SIP Trunk include monitoring?
Yes. Our NOC (Network Operations Center) continuously monitors your SIP connection, call quality, number of channels, failures, and security. We also provide dashboards with metrics and proactive alerts. This gives your company full visibility and helps prevent failures before they become issues.
What if my internet goes down? Will I lose the SIP Trunk?
Not necessarily. SIP Trunk can be configured with failover, forwarding to alternative numbers, and geographic redundancy. Please consult commercial terms. VulcaNet can also provide multiple SIP routes and recommend ISPs with dedicated links to ensure availability. It is possible to keep operations stable even in cases of failure with the primary provider.
Does VulcaNet offer technical support?
Yes, and it is not just any support. Our service is provided by specialized engineers and advanced-level technicians with deep expertise in Telecom and IP Networks. We do not use outsourced call centers. Support is available during business hours and, for customers with a special contract, we operate 24×7 with an on-call team.

FAQ
How much does VulcaNet’s SIP Trunk cost?
VulcaNet’s plans are flexible and adaptable to the size and needs of each company. You can sign up starting from 5 voice channels. Pricing varies according to the number of simultaneous channels, estimated usage, additional features (such as Voice API, IVR, portability, 0800, among others), and the type of support desired (with or without an SLA). We provide a personalized, no-obligation quote.
Is there a contractual commitment for VulcaNet’s SIP Trunk?
Yes. Our plans can be contracted with a minimum 12-month term, which ensures full flexibility for your company. You can adjust or cancel the service at any time, with full transparency. We also offer optional longer-term plans with greater commercial benefits, such as progressive discounts or free consulting.

Yes. VulcaNet serves companies of all sizes, including MEIs. SIP Trunk is ideal for small offices, service providers, and self-employed professionals who use a Virtual PBX or IP Phone to serve customers with quality and professionalism. You only need a valid CNPJ and to provide the standard documents.
How do I receive the SIP Trunk invoice?
The invoice is sent monthly by email and can also be accessed through the customer portal. Payment can be made via bank slip (boleto) or PIX. We also offer recurring credit card payment options for companies that prefer speed and control.
Difference Between SIP Trunk and Other Technologies
FAQ
What is the difference between SIP Trunk and E1?
SIP Trunk is more modern, flexible, and cost-effective than E1. While E1 requires physical cards, cabling, and specific installations, SIP Trunk operates entirely over IP, via the internet. SIP allows you to contract from 1 to hundreds of channels, with activation in minutes, while E1 offers fixed blocks of 30 channels and requires a longer deployment time. In addition, SIP is scalable, cheaper, and easier to maintain.
Is SIP Trunk better than a traditional carrier?
Yes. SIP Trunk offers more control, better cost-effectiveness, and technological freedom. Traditional carriers often have rigid structures, fixed plans, slow support, and integration limitations. VulcaNet’s SIP Trunk, on the other hand, provides direct support from engineers, API integration, tailored plans, and a guaranteed SLA. It is a technological evolution for companies that want autonomy and performance.
Does SIP Trunk replace the company mobile phone?
Not exactly. SIP Trunking is recommended for landline calls (reception, IVR, centralized service), while mobile phones meet the team’s mobility needs. However, it is possible to forward SIP calls to mobile numbers or integrate the PBX with softphones and apps, allowing employees to use SIP on their mobile phones with professional-quality audio.
Does SIP Trunk work without a carrier?
No. SIP Trunk requires a carrier authorized by Anatel, such as VulcaNet, to connect your internal network to the public switched telephone network (STFC). This ensures quality, legal validity, and specialized technical support. “Carrierless” solutions generally do not have official numbering or portability.
Is SIP Trunk the same as a VoIP link?
Although similar, SIP Trunk is more comprehensive than a conventional VoIP link. It offers simultaneous channels with control, call detail records, failover, IP PBX integration, APIs, and certified support. Standard VoIP, on the other hand, usually does not have professional-grade infrastructure, technical support, or formal contracts.
Is SIP Trunk suitable for small businesses?
Yes. SIP Trunk is ideal for companies of any size, including small businesses looking to professionalize communication and reduce costs. With plans starting from a single channel, it is possible to activate a high-quality telephony solution without major investments. It is ideal for offices, clinics, agencies, stores, and service providers.
