I loved OnSIP's approach of offering an easy-to-use cloud service that works with any SIP phone. ... It’s clear they stay focused on what customers want.
I congratulate the ones that do the hiring [at OnSIP] for finding a team of awesome and knowledgeable employees.
With every call, they’ve been patient, friendly, and incredibly helpful ... I would recommend OnSIP based on their customer service alone.
You have to search long and hard for a service that comes near to OnSIP in terms of friendly and responsive support, pricing, and reliability.
