  1. Too Expensive

    Just because SIP is new technology, doesn’t necessarily mean it is expensive. In fact, for the majority of businesses, SIP services are a cost-effective solution.

    A study by TalkTalk found that 96% of businesses surveyed which had already made the switch were making cost savings (source: TalkTalk and Censuswide survey based on 1,000 UK decision makers).

  2. Poor Call Quality

    Many people have experienced VoIP services at home, thanks to apps like Skype. Though these apps are very useful, the unreliable level of call quality would cause problems for businesses, affecting both working efficiency and company image.

    However, providing you have the right amount of bandwidth allocated, business-grade SIP services provide call quality which is comparable to ISDN lines used by standard business phone systems.

  4. Switching is Too Much Hassle

    Previously, replacing telephony systems were time and resource intensive, especially with those long lead times. This is no longer the case; making the switch to SIP trunks couldn’t be easier as it has the potential to use your existing fibre broadband connection.

  5. SIP is Risky

    It is understandable that decision makers perceive SIP as a risk to their business because it is new technology and they are unfamiliar with it.

    However, IP and VoIP services are currently being utilised by many businesses – research shows that 35% of companies have successfully adopted the technology.

  6. I Won’t Own My Advertised Number Anymore

    Any existing telephone number from any supplier can be imported onto a SIP trunking service. Numbers are stored in a central database; therefore, you can use any geographical or international number.
