Businesses cannot afford to ignore SIP trunks

With BT announcing a firm date to switch off all its PSTN and ISDN services, we think UK businesses should consider switching to a SIP service sooner rather than later.

During a BT Group Q3 2014/15 results announcement, CEO Gavin Patterson stated that BT intends to migrate all its customers onto the IP network by 2025.

He said: “We already serve many thousands of customers in businesses using IP. Our goal is that by 2025, all of our voice customers will be served using IP with a premises solution and will migrate off the traditional telephony platform.” 

This gives businesses 10 years to migrate from their traditional ISDN and PSTN services, but many are getting the ball rolling now, not only to avoid their existing voice services becoming obsolete but also to ensure they are enjoy the benefits of SIP sooner.

Many of our customers have migrated to SIP trunk technology and have seen their phone bills reduced by up to 75%. That amounts to thousands of pounds when you are a large business but is not an inconsiderable saving it you are an SME. 

These savings are achieved by using existing data connections*, such as Internet leased lines, EFM, FTTP and FFTC, for voice traffic as the cost of calls is less to both landlines and mobiles, and, indeed, in some cases are free. SIP channels are also cheaper to rent than traditional ISDN and PSTN connections and can be rapidly added as needed.

But the benefits do not end there. Business continuity is also a factor - in the event of a line failure, the redirection on a SIP service will take just minutes rather than the hours needed on PSTN or ISDN. 

Businesses can present a specific geographical presence by choosing which number(s) your customers call you on as well as which number is displayed when you call them. You can also retain these numbers if your business relocates.

So with all these positives listed above, why aren’t more businesses migrating to SIP?

For some, their current telephone system provider maybe telling them that their existing system won’t support SIP or that it is too cost prohibitive. But do not be deterred. We provide gateways to convert ISDN or PSTN services to SIP.

To conclude, this is going to happen. There is a date in black and white, and we cannot ignore the change, but why would anyone want to when the benefits are so impressive?

*swcomms only deploys SIP trunks on connections that segregate the voice such as an assured service (with guaranteed voice quality) or on a service that can provide sufficient bandwidth.
