SIP Trunks

SIP Trunks for Voice Calls Offer Huge Savings

If you still use ISDN or traditional phone lines, you’re missing out on the powerful benefits of SIP Trunks. Benefits as immediate as savings on call costs to longterm benefits such as being free to move office and take your number with you and having redundancy in case of emergency.

SIP Trunks are an additional voice channel in addition to your ISDN channels, but instead of being physically connected to your local exchange, they transmit voice via your internet connection, offering you inclusive calling minutes and free site to site communications.

In a nutshell, as long as you have internet connectivity, and if you’ve partnered with us to get connected you will have, you’ll be able to make lower cost voice calls to anywhere in the world.

More Power with SIP

Because SIP Trunks sit on your network, you can access the many benefits of an IP-connected system including reporting, analysis and support. Call logging can even be integrated into your CRM.

Combined with the feature-rich power of a Mitel telephone system, you can transform an inbound customer call into a powerful, pleasant experience with intelligent call routing, on-hold messaging, call distribution to designated teams whilst remote workers never have to miss a call into the office again.

You can get all of this at a lower cost than your existing system.
