Myth one: ‘SIP trunking is untested technology’

The technology underpinning SIP trunking is well established and standardised.

Around one million SIP trunks are currently used in the UK, with this figure expected to triple by 2018.

Myth two: ‘Deploying SIP trunking is difficult’

Integrating SIP trunking into a company’s phone network is often easier than with ISDN.

Also, a reputable SIP trunking provider will provide full on-site support.

Myth three: ‘Cost savings are marginal’

Public calls made over SIP trunking are cheaper than those made over ISDN and internal calls (including those between international branches) can be free.

Enterprise SIP trunking can generally result in more than 60% savings over existing infrastructures and trunking services.

Rationalising ISDN lines and PBXs can bring further savings.

Myth four: ‘Security is an issue’

SIP offers various tools that work in conjunction with firewalls including monitoring, alerting and portal control.

If the SIP trunking provider operates its own national network, even greater security is assured.

Myth five: ‘Choosing SIP means having to compromise on quality of service’

The QoS offered by SIP can match that offered by traditional voice services.

Myth six: ‘SIP is less reliable than ISDN’

SIP can provide 100% uptime on your telephony.

Myth seven: ‘SIP is less robust than ISDN’

Enterprise SIP trunking enables your customer’s PBX to be hosted in the cloud, offering a speedy disaster recovery solution. ISDN failures can take days to fix.

Myth eight: ‘SIP trunking makes the telephony network more complex’

By unifying voice, multimedia and internet, SIP simplifies the telephony network and enables you to rationalise the number of ISDN lines and PBXs.

Myth nine: ‘The number of channels available with SIP trunking is limited’

There is no limit on the number of SIP channels available.

Myth ten: ‘SIP is limited by geographical area code’

Unlike ISDN, SIP telephone numbers are not tied to a site. SIP offers full number portability.
