Seven Benefits of a SIP Trunking Service

When you resell SIP trunking services, you will be able to offer your customers these seven primary benefits. Let’s take a look.


SIP trunking services easily scale to meet your needs, allowing additional trunks and channels with DID to enabled in a matter of minutes, not weeks, like traditional PSTN phone lines.

Consolidated Network Management

The management and monitoring of the PSTN network is no longer needed with SIP trunking, since SIP trunks run over your data network. This eliminates your need to maintain and support two different networks.


When using SIP trunks, you can use multiple providers, giving you failover capabilities in case your network connection goes down, in the event there is an outage.


SIP trunking services utilize DIDs (Direct Inward Dials) that allows each employee can have their own SIP line, providing you with great capability and flexibility in your calling.
