SBC as a Service PakistanManaged AudioCodes & Ribbon SBCs
Microsoft and Zoom both require a certified session border controller before your carrier trunk can reach Teams or Zoom Phone. But buying one means a capital purchase, channel licenses, a second unit for failover, and an engineer who knows SIP. Capstar Solutions runs the SBC for you instead, as a subscription, and handles the carrier coordination, certificates, and security hardening that break most first deployments.
Why Can’t Teams or Zoom Calling Run Without an SBC?
Once your carrier trunk touches the internet, your phone system is exposed to attack. And your carrier, your PBX, and your cloud platform each speak a slightly different version of SIP. A session border controller (SBC) sits at the edge of your network and solves both problems. Without one, Microsoft Teams Direct Routing and Zoom Phone BYOC won’t connect at all.
It Translates
Converts between your carrier, PBX, Teams, and Zoom, so every call connects.
It Guards
Works as a voice-built firewall, keeping attackers and toll fraud out.
Your existing firewall can’t do this job. It doesn’t read SIP, it can’t renegotiate codecs, and it won’t spot a toll-fraud pattern until the bill arrives. A dedicated SBC service protects and manages every SIP session on your network. It keeps voice, video and instant messaging secure across public and private networks, following the architecture set out in IETF RFC 5853. Here is what the session border controller Pakistan enterprises get from Capstar Solutions does for you on every call.
Most gateway problems are cabling, signalling or dial-plan problems. That is where our engineering time goes.
Calls that Connect the First Time
Your carrier, Teams, Zoom and your old PBX each speak their own dialect of SIP. The SBC rewrites headers and remaps codecs as each call passes through, so calls go through instead of failing with errors your team has to chase.

An Internal Network Outsiders Can't See
Outsiders only ever see the SBC (this is called topology hiding). Your PBX addresses, extensions, and server names never leave your network, so attackers have nothing to map.
Clear Calls Even at Peak Hour
Your SBC caps how many calls each trunk, site, and user can run at once. Call quality stays clear when the network is busy, and one hijacked account can't tie up all your lines.
Conversations No One Can Overhear
TLS locks down call setup, and SRTP encrypts the audio itself. Microsoft Teams Direct Routing and Zoom Phone BYOC both require this encryption before they will carry your calls.
Calling Working Through an Outage
A second SBC and a second carrier trunk take over automatically if the main path fails. Self-bought deployments often drop this to save money. Capstar includes it in the design wherever your business needs it.
Centrally manage and secure your voice and video communications
There is no doubt that VoIP and Unified Communications have made your business more efficient and connected. However, delivering these solutions traditionally meant purchasing purpose-built appliances and proprietary software licenses for each location. It would not be uncommon for you to spend a considerable amount of money installing new circuits, and then spend days configuring them.
Our Session Border Controller as a Service (SBC) solution gives you a more agile, centrally managed approach to network deployments and management. With Enterprise Orchestration, you can manage seasonal demand surges without investing in new equipment, and deliver communications 24×7. It’s all orchestrated by our experts, who have been managing customer networks for over two decades. With our SBC solution, you can use our flexible subscription-based pricing to scale up or down easily as your business needs change.
How does SBC work?
The SBC service protects and manages all of your SIP sessions across your network like a traffic cop. As part of the solution, you have access to voice, video, instant messaging services that are securely delivered across both public and private networks. The configuration and management are handled by us since it is fully managed and hosted.
