SIP Trunking vs ISDN
| SIP Trunking | ISDN | |
|---|---|---|
| Circuits/Hardware | SIP TrunkingAll connections are virtual, limited only by bandwidth available. Session Border Controllers (SBC) may be required for security and come at an additional cost. | ISDNAll connections are physical, requiring manual connectivity and expensive termination hardware. |
| Scale/Growth | SIP TrunkingEasily scalable, a quick software configuration can add new channels and can offer automatic and on-demand burst capabilities. | ISDNGrowing the network requires the installation of new circuits and additional hardware. For PRI, the increment is 23 voice channels. |
| Backup/Redundancy | SIP TrunkingAutomatic IP re-routing enables the distribution of PSTN connectivity to sites with limited or network redundancy. It can also be designed to retain PSTN reach in the event of hardware loss. | ISDNThe provision of backup circuits to remote sites in an IPT-distributed architecture can negatively impact ROI. The only way to accommodate hardware loss is to structure excess capacity with associated costs. |
| Cost | SIP TrunkingVarious pricing models – such as on-demand – are available, with the cost significantly lower in comparison to PRI circuits. | ISDNThe cost of PRI is typically on a per circuit, per month basis, with an increase in voice channel requirements available in fixed increments. |
| Capacity Planning | SIP TrunkingWhile lead time is always important, extra capacity can often be added with a simple software upgrade. In addition, it is often possible for providers to accommodate temporary burst capabilities for periods of increased activity. | ISDNDue to the need to arrange installation of circuits and termination hardware, any additional capacity requirements must be planned well in advance. |
| Disaster Recovery / Business Continuity | SIP TrunkingAutomatic call re-routing to pre-defined locations is simple, quick and affordable. Plus, SIP trunking is capable of accommodating diversity across service providers. | ISDNDiverting calls to alternative locations can be complex and expensive. |
Benefits of SIP Trunking
Cost saving
Thanks to multi-modal communication capability, SIP trunking enables you to save more that 30% on monthly telecommunications costs.
Trunk aggregation
By centralizing and eliminating redundant connections, you are able to use idle connections in one location for calls at another, thereby offering increased flexibility over traditional PRI circuits.
Flexibility
Depending on the needs of your organisation, the ability to add or reduce connection capacity is simple, thereby increasing the flexibility of the service you provide.
Quality
By keeping communications data on pure IP connections as opposed to T1 PRI connections, SIP trunking offers improved voice and video quality, delivering almost HD-like audio.
Simplified billing
By aggregating all the voice and data services into one product, you can take advantage of reduced administration with simplified billing.

Due to our expansion we have had to move offices a few times, luckily being on cloud meant we are not restricted to the BT exchange and have always managed to take our number with us. KomTek ensured there is no downtime, I am very impressed with their project management skills.

Chris Clancey
I knew very little about KomTek apart from their website, but from my calculations of looking at our current bills etc, I saw that they were definitely one of the cheapest I could find. We picked the best product for our needs and ended up saving ourselves anywhere between £70-100/month.

Selecting Data Circuits
If high-quality calls are a requirement for your business, it’s important you support your network with the right data circuits. Standard ADSL is ill-equipped for the delivery of voice data, not least when a congested network can cause significant disruption to your calls. Instead, we recommend investing in either an Ethernet circuit, whose stability can accommodate a number of simultaneous calls, SDSL, SDSLM, or Voice-Approved ADSL.
Simply contact KomTek today to discuss the best option for your business. -
SIP Trunking Explained
Session Initiation Protocol – or SIP – is a signaling communications protocol commonly used by internet telephony service providers (ITSP) to deliver voice and video calls over IP networks. It both establishes and closes calls over a network, and works alongside other protocols in transporting thousands of data packets containing audio and video information. Unlike such services as Skype, business SIP trunks provide ISDN30e quality – far superior in terms of performance and stability.
-
The Numbers You Need
One of the main advantages of choosing business SIP trunking from KomTek lies in the ability to have numbers from the dialing codes you want to be delivered directly to your office, regardless of location. The ability to centralised numbers from such diverse places as London, Manchester, Birmingham, and Glasgow to a single hub ensures that establishing a nationwide presence for your company is simple. Just specify the dialing codes you desire, and leave us to do the rest.
-
Disaster Recovery
Telephony downtime can damage both the finances and reputation of your business. With Session Initiation Protocol (SIP), there is a Disaster Recovery strategy ready to support you should the worst happen.
The first level of resilience in SIP trunking Disaster Recovery is the ability to reroute calls to a backup IP address and/or location. The second level is the ability to divert calls to backup ISDN30e or local telephone numbers on a Direct Dial In (DDI) to DDI basis. With such means of resilience available, there is no reason for users to even be aware of any issues.
You can discuss your Disaster Recovery options with our engineers today. They will be happy to talk you through the full selection of available services. -
Quality Assured
This improved quality is assured thanks to the manner of delivery; each IP data packet arrives in the correct order and without delay, one after the other. Thanks to SIP trunking services from KomTek, this steady stream of delivery means that packet loss, time delays, and interruptions in delivery are never experienced. But how do we achieve this?If you’ve ever experienced delays or problems in communication over IP, the most common issue stems from your internet service provider being unable to guarantee that your data will be forwarded onto your ITSP without delays. Instead, it’s often the case that your data will pass through some networks before finally reaching your ITSP, with a corresponding deterioration in quality.
With XINIXWORLD, there are no such issues. As a provider of all the services needed for successful communication, there is no delay and no compromising in quality. Our SIP trunking services ensure the same ISDN30e call quality, along with the ease and value for money to keep your business at the forefront of telecommunications.
