basics to know

VoIP – Voice Over Internet Protocol – provides a variety of benefits over traditional phone networks, including lower costs, more flexibility, and more convenience, but the VoIP solutions offered by a legacy phone company carry drawbacks such as limited coverage and long-term, inflexible contracts.

The good news is that SIP trunking solves many of these issues. With SIP trunks, VoIP calls can run through a cloud-based provider that routes calls efficiently based on location to deliver premium call quality and global coverage. Plus, cloud-based providers offer flexible contracts and pricing models that make it possible to test their solutions while you still have phone service through a traditional telecom.

Benefits to backup sIP trunks

Broader coverage
- Adding a backup SIP trunking solution lets you make calls
  even when your main provider can’t deliver, either because of a technical
  failure or because of limited geographical coverage. Because SIP trunking
  providers have relationships with multiple carrier networks, there is no single
  point of failure.
Risk-free, low-cost testing
- Many SIP trunking providers offer free setup and simple pay-as-you-go pricing, so it won’t cost anything to put this backup solution in place, and you can try it out at whatever scale you want to keep expenses down.
Added capacity, just when you need it
- If you’re stuck in a long-term contract with a traditional phone network that limits your channels or phone numbers, using a backup SIP trunking solution can offer flexibility. For instance, if your business faces increased call volumes during the holidays, a SIP trunk allows you to quickly scale up and then scale back down afterward without renegotiating contracts or dealing with administrative fees.
Easy setup and instant provisioning
- Testing a cloud-based SIP trunking solution tends to be an easy process, with setup taking just a few minutes. Rather than dealing with complex programming or enduring wait times for phone number purchase, you can often instantly search and provision numbers to match your needs for fixed, mobile, or toll-free numbers. You can also get unlimited call capacity with every number, and every line can be added remotely. Zentrunk, for instance, lets you set up a trunk, link your numbers to the trunk, and send and receive calls on your VoIP Infrastructure in less than five minutes.

Conclusion

Overall, SIP trunking providers tend to be simple to set up quickly and with minimal risk. You can experience what it’s like to use SIP trunks without getting locked into long-term contracts, and you can then decide what type of provider you’d like to move forward with once your existing contract ends. And in doing so, you get the benefit of a backup solution that provides a security blanket for your setup in the event something goes wrong with your existing carrier.
