SIP Trunk considerations

Call Recording
SIP Trunk channels

In many cases, the number of channels needed for SIP Trunking can be guesswork and businesses end up sizing trunks on a 'just in case' basis. This leads to higher costs.

Callroute's unique autoscaling feature enables businesses to increase capacity on-demand - without having to pay to reserve the capacity!

What's more, our per channel pricing enables pooled capacity. This means that if businesses have offices in different time zones or different staff calling demands, the capacity can float across the global estate rather than duplication in different geographies and offices. This offers significant cost savings. 

Analytics and Reports
Futureproofing your SIP Trunk solution

Lengthy contracts and future-proofing are other important considerations for SIP Trunk providers. Many businesses wish to migrate to new services such as Microsoft Teams later down the line.

Callroute has this covered with simple pay as you go monthly contracts meaning no long term commitments. The ability to float trunk capacity across UCaaS platforms such as Microsoft Teams means you can add services when your business is ready and create hybrid environments. Integrate in minutes with our self serve portal.
