BT Cloud Voice

Should you migrate BT ISDN to Cloud Voice or SIP?

The eventual demise of BT ISDN services is a growing concern around the IT Management community. The question is why?

BT Cloud Voice and BT SIP are two technologies based on the IP product set with huge capability. So where is the concern?

ISDN is a tried and trusted technology which, in the main, is highly robust and All businesses will eventually migrate from ISDN.predictable from the perspective of performance. Businesses implementing ISDN-2 or ISDN-30 often do not think too hard about their decision-making process. With Cloud Voice and SIP, the thought process must be different to meet the service level guarantees required within a business environment.



What are the top considerations when migrating from ISDN to SIP-based IP products?

Connectivity - the circuit must offer sufficient bandwidth and meet latency / jitter requirements to support VoIP, video, and collaboration. Our advice would be to leverage the same IP / SIP / Cloud provider for core office connectivity as this ensures a good end to end SLA, security and predictable performance.
Support - not only does using a single provider ensure good traffic performance but also ensures support is covered on an end to end basis across all aspects of your service. The BT Cloud Voice platform is installed and supported by engineers located on the same team as BT connectivity services.
Capital cost - organisations which have recently invested in hardware will, for obvious reasons, need to utilise their investment. With BT Cloud Voice, BT mandate the use of BT bought and supported hardware rendering existing equipment ‘for sale’. For some businesses, their financial team may not take too kindly if recently procured hardware is not fully used over term.
Loss of control - many businesses mandate a need to stay in control of their own infrastructure. Where expertise and investment have been built up over many years, there is a reluctance to migrate these human resources to the cloud.
Cost savings - investment in the hardware required to terminate ISDN together with monthly rental costs means traditional telephony is often not cheap. With cloud services becoming ever more cost-effective, a licence based system will generally result in an excellent ROI (Return on Investment).
Flexibility and efficiency - with ISDN, adding further channels requires procuring additional circuits - i.e., ISDN2 or ISDN30. Cloud Voice provides a capability to simply add further concurrent calls without the need to order physical circuits. Whats more, cloud applications update automatically meaning you’re always using the latest software - adding features is simplistic via portal access.
Features - the Cloud and SIP are so much more than telephone calls. Today, video conferencing, collaboration, messaging and more are creating serious business efficiency.
How to make a phased transition from ISDN to SIP?
  • BT Cloud Voice - A fully featured cloud product with licence based access, handsets, and sharer call packages.
  • BT SIP with call bundles and pence per minute rates.
  • BT ISDN to SIP conversion via a hardware device.
With the end of ISDN occurring at some point in the near future, a decision needs to be made whether or not your organisation will adopt a transition plan or complete a 'big bang' replacement. BT offer an ISDN to SIP conversion device which will essentially terminate the interface of your ISDN circuits. The hardware (manufactured by Samsung) converts the ISDN signal to SIP over BTNet Internet circuits.
Once converted, your business can leverage the cost of your Internet circuit and save on the removal of your physical BT ISDN circuits but maintain the same setup. In some respects, the interim conversion of ISDN makes sense since you’ll be able to retain any capital cost hardware which is not end of life until your business is ready for a hardware refresh.

What could go wrong?

SIP via trunking or an outsourced Cloud product does, as we know, offers significant benefits. Where IP typically falls short, the impact to your business could be significant.

Why BT Cloud Voice vs on Premise BT SIP?

This first reason to consider an end to end managed cloud service is typically where there is a need is to fully outsource. Whether or not your organisation is well positioned to fully outsource is dependent on current investment in legacy and current IP technologies.
We've discussed investments made in capital cost on-premise equipment that may create a lack of appetite to fully outsource, especially from your finance department. However, just as hybrid networking exists on the WAN, our architecture often consists of a hybrid of technology services including legacy ISDN, Cloud and vanilla SIP trunking.
The goal should be to always align the specifics of your organisation with the right capability, migration plan, technology, and budget.
