Making Emergency Calls

We will provide access to 999/112 public emergency call services and will take all reasonable steps to give you uninterrupted access to these services. Occasionally, services may become unavailable due to issues that are outside our control, such as a power outage or internet connection failure. At these times, public emergency call services will also be unavailable.

Please be aware that services may not automatically provide your phone number and location details to the operator of 999/112 emergency call services – you may need to give this information verbally.

Our Policy on Nuisance Calls

It’s a criminal offence to make nuisance calls and it breaks our Terms and Conditions. If you use our Services to make nuisance calls, your account will be suspended while we investigate and then closed down if you have offended. Your activities may also be reported to Ofcom and the police. Numbers need to be registered in our database to pass Calling Line Identity presentation and you will need to prove ownership of any additional numbers used.

Reducing Incoming Nuisance Calls

There are a number of steps you can take to cut nuisance calls – for example:

  • Sign up for the Telephone Preference Service (TPS), a free service and the official opt-out register for unsolicited sales and marketing calls. By law, no organisation can call a TPS-registered number without the permission of the number’s owner.

  • Use our call barring service, which enables you to filter out anonymous callers, international callers and numbers that you have blacklisted. You’ll need to contact our customer service team to set up call barring.

Following Best Practice for Security

  • Passwords

    You should ensure that our password policy is always followed closely and that all user-generated passwords adhere to our documented recommendations.

  • Restricting calls by user

    Our services enable you to limit the locations users are able to call – for example to those destinations that are common to the business. Calls can also be restricted according to number type and time of day. We can help you to set up your policy and add or remove different locations.

Our security system automatically blacklists risky or potentially fraudulent destinations. If required, system administrators can enable specific destinations in their control panel.

  • Controlling remote access calls

    Remote access to your PBX is prevented by default to limit the potential for fraud, but you can enable remote access functionality by contacting our customer service team.

  • Limiting spend by user

Our services allow your system administrator to limit the total minutes/spend of calls per user and our customer service team can help you set up a call plan that meets business needs. In addition, we can provision a call usage monitoring service that alerts administrators to potential fraud and blocks any problem account to minimise risk.

  • Auto-provisioning handsets

    All the handsets we provide are dispatched with highly secure passwords, which are available from our customer service team. Please also ensure that your own processes follow our password policy.

  • Limiting the number of channels per user

    After assessing the call usage patterns of your users, our Services allow administrators to set a limit on the number of concurrent calls a user can make.

For example, setting the limit to 2 channels will allow the user to make a three-way call – but if the user frequently has multiple lines on hold, this limit will need to be increased.

  • Limiting access to known IP addresses

    Administrators can limit system access to known IP addresses by providing a whitelist to our support team. Sip trunks and peer connections can also be locked to specific IP addresses.

  • Validating Outbound Calls

    Outbound calls need authentication before they can be placed – please bear in mind you will not be able to make or receive any calls using our service without configuring the correct authorisation.

  • Aligning Channel Numbers with Business Needs

    Our customer service team will work with administrators to determine the number of channels you need to meet peak call usage.

Ensuring Network Resiliency

  • Our network infrastructure uses Tier 1 carriers and communication providers, and multiple Internet exchanges to connect resiliently to the Internet.

  • Our data centres are resiliently connected using redundant links.
