Three Reasons Why it's Time to Move Away from ISDN to SIP

BT’s recent announcement, which states that by 2025 all of their customers will be using IP Voice, undoubtedly shows why IT is increasingly beginning to shun traditional ISDN channels and the demand for SIP is steadily growing.

SIP trunking isn’t the new tech on the block anymore, but its expansion has reached a tipping point, with growing confidence in its capabilities and the ever expanding list of benefits making a compelling business case.

High speed internet is an essential component for ensuring a stable SIP connected network. Significant improvements in broadband speeds, in particular upstream speeds, have been a real catalyst in kick starting the SIP market.

The announcement from BT is one of the many reasons why as a consumer of ISDN services there has never been a better time to move to SIP.

So why should you make the move?

1. Flexibility:

• You can scale up and down whenever you want, whether seasonal or short-term
• The number of SIP channels can be increased straight away, with no lengthy installation periods
• If you move location, you can take your numbers with you anywhere in the world with no need for expensive call forwarding

2. Improved business continuity:

• SIP offers built-in business continuity, with proactively monitored services that protect your business
• You can route your calls to any number at any site
• Fraud management options, such as daily and weekly thresholds that if exceeded will place a bar on the service, equally you can have alerts when it hits a certain percentage. You can also block calls to certain international locations along with certain types of premium or higher rate calls.

3. Cost effective:

• You can save money on call costs and line rental – with SIP, as a cloud based service, the physical overheads are removed
• Benefit from lower call rates across your entire estate
• Rationalise your estate with a centralised SIP solution, which allows you to reduce your overall line requirement
• Free internal calls
