The collaboration will also extend Colt's existing Direct Routing solution which uses AudioCodes' Microsoft-certified session border controllers.
"Colt has partnered with AudioCodes in recent months to provide Direct Routing functionality to our Microsoft Teams customers," said Rui Ferraz, global product manager of unified and intelligent communications at Colt.
"For us, as a service provider, it was a perfectly natural progression to deepen our alliance with AudioCodes on our integration with Microsoft Operator Connect by leveraging their acknowledged expertise in the field."
Colt also used the AudioCodes Live Cloud software-as-a-service (SaaS) solution to give its resellers and customers a multi-tenant, multi-tier management portal that streamlines end customer onboarding, and enables them to offer a complete connectivity solution for Microsoft Teams Phone System.
"AudioCodes Live Cloud is a true gamechanger thanks to its ability to enable service providers like Colt to offer a comprehensive portfolio for Microsoft Teams Phone System with rapid onboarding for their customers," added Lior Aldema, chief business officer at AudioCodes.
"As enterprises look to boost their productivity in the hybrid work era, service providers can confidently meet their customers' expectations for quick Microsoft Teams rollouts, all backed up by AudioCodes' proven track record in unified communications."
Colt customers can now use Microsoft Operator Connect to select Colt as a valid operator and connect to Colt calling services via the Microsoft Teams admin centre.
In addition, Colt's integration with Microsoft Operator Connect benefits from 24/7 monitoring from AudioCodes experts as well as direct peering through Microsoft Azure, with traffic exchanged directly between the two company's networks for added reliability.
