SIP trunking is the hardware that allows all your SIP-enabled devices to connect to the internet and begin communicating via VoIP. It’s also what ensures that there is no limit on your ability to place and receive calls, keeping that “unlimited” promise in check.
The SIP trunk is most likely located at your closest data center, though if you decide to install your own internal internet communication system, then you may prefer to have your own hardware installed for the business.
Once your SIP trunking is in place, you need to ensure that your devices are compatible with SIP and that your business will be able to seamlessly transition from standard phone calls onto your VoIP network.
For most modern office phones, SIP will already be enabled and will simply need to be set up by using a SIP dialing app. For iPhone users, there are third-party tools to integrate calling capabilities into the phone. For Android users, you’ll have built-in settings for registering devices with a SIP provider. In all cases, you may need to contact your VoIP provider for these credentials.
To drill down further, SIP phones are on-premises phones that can use the internet. SIP phones allow you to make video conference calls. A SIP client is a program installed on your computer or mobile device. It contains functionality and features for you to communicate. The most common types of SIP clients are those offered by VoIP service providers. However, if your devices are older, then you may find they need replacing.
