What is cloud hosted SBC?

Cloud hosted SBC allows you to get maximum efficiency from your VoIP solutions. It is a completely cloud-based solution. It has a simple fee schedule such as pay per user. It also allows you to take advantage of the so-called Direct Routing.


With cloud hosted SBC, you create a flexible and scalable communication network. You have the opportunity to benefit from all the possibilities of the cloud environment. You increase your performance and at the same time, you produce fast solutions. You can add value to all your existing services.


What does cloud hosted SBC mean?

Simple NAT and PAT are insufficient to address NAT traversal difficulties for VoIP traffic in general and SIP signaling in particular for a variety of fundamental reasons. The infrastructure and other voice Network resources used to transmit speech traffic for voice applications, such as telephony, wireless, landline, voice over IP, and voicemail, are referred to as the voice network.


A good design is necessary for a unified communications solution. The phrase "unified communications" (UC) refers to the combination of various business communication platforms. Among a select few motives:

  • A phone numbers of header fields must be included in accordance with the SIP Standard, some of which must include the IP Address where responses must be transmitted. The WAN-to-LAN device does not at all alleviate this issue because NAT and PAT only work on the IP headers and not the UDP Payload.

  • SIP integrates the media codec negotiation step inside an embedded protocol known as SDP in addition to handling the tasks of starting up, modifying, and terminating conversations (Session Description Protocol).

The majority of users have NAT- cloud based routers and firewalls, which may be a pain to set up if you don't have the necessary equipment. Due to the IP addresses of each device being encapsulated by VoIP protocols in the session layer packet and the fact that firewalls won't permit any session started from the open Internet to the private internal voice network.


Numerous issues arise as a result, including one-way or no audio. When facing various types of NAT across various firewall and routing for Microsoft Teams manufacturers, some measures to tackle this issue, such as STUN or changing end-users' routing for Microsoft Teams or firewalls, may not always work and turn into a support disaster.


Session border controller (SBC)

Tens of thousands of endpoints can receive service from the carrier-grade BVoIP SBC. If the "SIP proxy" server and port are configured on phone system or other SIP devices and pointed to the SBC, all SIP packet rewriting for NAT support is taken care of automatically. As a result, there is no longer a requirement for STUN, sbc2TURN, ICE, VPN, Tunnel, or any other NAT handling technique.


When one or more VoIP endpoints (such as analog phone numbers adapters, gateways, or IP phone system) are in a NAT environment, the Session Border Controller SBC enables VoIP sessions to be successful. Our solution dramatically simplifies your deployment by eliminating all the hassle associated with linking remote devices back to a SIP server.


Our SBC solution completely automates NAT traversal and makes it easy for BVoIP partners to implement their systems on the customer's premises with minimal maintenance and interaction. Security is yet another crucial concern that is handled in addition to NAT traversal. The SBC can control DOS, DDOS, fast and slow attacks to assist safeguard the 3CX server from corrupted SIP packets and the Avalanche Restart effect.


Direct routing or certificied session border controllers


To verify that certain Session Border Controller SBC providers' SBCs support teams Direct Routing, microsoft certified works with certain SBC vendors. This is a data center situation. Together with each provider, microsoft certified:


  • Collaboratively develop SIP connectivity protocols. The developments in the data center are followed.

  • run thorough tests at a separate lab. Only tested and certified gadgets are used.

  • Conduct regular tests in both production and pre-production scenarios using all approved devices. The pre-production environments' validation of the hardware ensures that certified SBCs will function with updated versions of the cloud based teams Direct Routing code.

  • Create a collaborative support procedure with the SBC vendors.

When used with approved hardware, Microsoft calling plans only supports Phone System with Direct Routing. You must first get in touch with your certified SBC vendor's customer service if there are any problems. If necessary, the certified SBC vendor will escalate the problem through internal channels to Microsoft calls. In circumstances where a non-certified device is linked to the Phone System via Direct Routing,


Microsoft calling plans has the right to deny support requests. Customers must re-engage SBC vendors for support if Microsoft calls decides that a customer's Direct Routing issue is with a vendor's SBC device. Specific SBC firmware versions are given the certification.
