SIP Trunks are an IP-based alternative to PSTN and ISDN lines. The Internet or Leased Line connection is used to make and receive calls online and directly to the PSTN network.
SIP Trunks are a highly flexible service. They deliver quality and business continuity at a significantly lower cost than ISDN.
|Reduced costs||There are no significant install, setup and maintenance/upgrade costs.|
Typical savings – up to 50% on line rental and up to 25% on call costs (when compared to traditional ISDN services).
Internet-based calls and internal calls are free, even to international sites.
|Full scalability||Unlike traditional ISDN services, the number of SIP channels you have can be adjusted without infra-structure changes.|
If there is enough bandwidth to cater for extra channels, they can be available on a pay as you grow basis.
This solution is also perfect for seasonal voice demands such as sales campaigns etc. Extra lines can be temporary or permanent.
|Seamless continuity||SIP Trunks offer complete portability. They are also a great solution to support disaster recovery planning.|
They can immediately re-route calls to an alternative location (should an emergency happen), without incurring any call-forwarding charges.
There is also an option to keep your existing numbers when moving out of an area.
Our SIP Trunk service may be compatible with your current set up.
We can also move the PBX system to our secure data centres.
|Consistent quality||We provide an end-to-end service with 99.95% availability, supported by strong SLAs.|
