SIP Trunking: A Better Way to Make Business Calls
SIP Trunking: It’s the smarter way we’re making business calls these days. With clearer conversations, the flexibility to grow, and a kinder bill at the end of the month, it’s no wonder businesses are making the switch. See what all it is about.
What is SIP Trunking?
SIP trunking by Rozper bridges your business phone system to the public switched telephone network (PSTN) via the internet, eliminating the need for conventional lines. Without changing your existing setup, Rozper’s SIP trunk routes calls as data packets, leveraging VoIP technology. Our service seamlessly connects your on-premises phone system to the PSTN, ensuring efficient conversion and transmission of calls, both outbound and inbound, over a high-speed internet connection.
Troubleshooting Your SIP Trunking Problems
Connectivity Issues
Proper configuration of network settings is essential for SIP trunking. Examine your firewall settings, ensuring they're optimized. The connection between the SIP trunk and your IP-PBX should be flawless. Conducting periodic diagnostics can pinpoint issues, enabling prompt resolution.
Voice Quality Concerns
Continuous voice clarity is a must. Always monitor bandwidth consumption. Recognizing signs of jitter or latency early can prevent call quality degradation. Ensuring codec compatibility across all communication devices is also crucial.
Call Establishment Failures
Establishing a call should be seamless. Dive deep into your SIP signaling logs, looking for any inconsistencies or errors. Ensure that the system's configurations align with the latest standards. Keeping authentication credentials accurate and updated is equally important.
Intermittent Call Drops
A call should be stable once established. Keeping a close watch on session timers and RTP streams is fundamental. Network traffic can fluctuate, so being proactive in monitoring and addressing potential congestions can make a world of difference.
Registration Failures
Devices should register without hitches. Double-check all device configurations for inconsistencies. It's essential to note that IP conflicts or certain restrictions might pose challenges. Verifying the accuracy of account credentials can save you a lot of headaches.
Security and Authentication
SIP trunking requires top-notch security. Unauthorized access can create myriad issues. By regularly updating passwords, employing encryption techniques, and maintaining robust security protocols, you can ensure the integrity and safety of your SIP trunk.
How Does SIP Trunking Work?
Here is a step-by-step overview of how a SIP trunk from Rozper handles a cal:
- An employee picks up their desk phone for an outbound call.
- The call request is processed by your on-site phone system, leading it via your LAN to the SIP trunk provided by Rozper.
- Through the internet, Rozper accepts the call request, transitioning the digital audio into an analog format suitable for the PSTN.
- On the PSTN, the call is established like any conventional call.
- The SIP trunk then channels the call over the web to your internal phone system.
- In the context of an incoming call, the mechanism is essentially inverted. Rozper first intercepts the analog call, turning it into its digital counterpart.
- Based on the dialed inbound number, your phone infrastructure determines the specific desk phone to alert.
- As the phone is attended to, the communication connection becomes operational.
Benefits of Rozper's SIP Trunking
There are many compelling reasons for businesses to adopt Rozper SIP trunking services:
Cost Savings
SIP trunking removes the need for individual PSTN lines. Calls are delivered over a shared IP connection, saving up to 80% compared to traditional lines.
Scalability
It's easy to add or remove capacity as your needs change. You simply pay for the number of simultaneous calls you need. This on-demand scalability isn't possible with legacy phone lines.
Flexibility
Your phones can be located anywhere with an internet connection. This enables remote workers and multi-site offices to be connected through your phone system.
Advanced Features
Rozper SIP trunks provide access to VoIP features not possible on conventional phone lines, like auto-attendants, voicemail to email, call analytics, and more.
Business Continuity
In the event of an internet interruption at your office, Rozper can automatically reroute calls to cell phones or alternate sites to maintain continuity.
Simplified Management
With Rozper SIP trunking, you only need to manage a single trunk rather than hundreds of individual phone lines. This streamlines adds, moves, and changes.
The Different Types of SIP Trunks from Rozper
Rozper offers a few different variations of SIP trunks:
Analog SIP Trunks
Rozper's analog SIP trunks convert PSTN calls into analog voice signals before sending them over the internet. This allows connectivity to traditional analog phones, fax machines, alarms systems, and other analog devices.
Digital SIP Trunks
Rozper's digital SIP trunks maintain calls in a native digital format end-to-end without analog conversion. This method not only preserves voice quality but also requires SIP-enabled IP phones for seamless communication.
Voice over IP SIP Trunks
Rozper's VoIP SIP trunks connect your SIP-enabled VoIP phone system directly to our VoIP service. These trunks carry calls as VoIP data packets end to end without circuit-switching. This is Rozper's most popular SIP trunking solution.

How to Choose the Right SIP Trunk
Here are some important factors to consider when selecting a SIP trunking service:
- Assess your calling needs - How many concurrent calls do you need to support? Will you be using toll-free numbers or local DIDs? This will determine if you need a shared or dedicated SIP trunk.
- Look at build vs buy - A PBX vendor will likely want to sell you their proprietary SIP trunk, but you can often save money buying a trunk from an ITSP (Internet Telephony Service Provider). However, a vendor trunk may offer tighter integration.
- Check provider reputation - Go with established, reputable ITSPs like Nextiva, RingCentral, Vonage, etc. Check reviews and uptime stats. Avoid unknown, cheap providers.
- Verify SLA commitments - Look for uptime guarantees, metrics around latency, jitter, packet loss. 24/7 support is preferred.
- Assess security - Encryption, SIP over TLS, fraud protection. Make sure the provider has protections in place.
- Do test calls - Do trial calls before deploying to check voice quality and reliability. Make calls during peak hours.
