How Will Your New SIP Phone System Work?

In practice, your new SIP phone system works exactly like your traditional business phone system, but much faster, and with greater flexibility.

A SIP trunk is effectively a cloud-based version of your analogue phone line. So instead of multiple expensive phone connections, your teams can access your existing PBX system via the internet. They can route their unique phone numbers directly to their smartphone, without any call restrictions of the old copper network.
