OnSIP overview
What is OnSIP?
OnSIP is a softphone and private branch exchange (PBX) solution that helps businesses to streamline operations related to call recording, transfers, monitoring, reporting and more. It allows companies to utilize the desktop or mobile applications to conduct HD video or voice conferences as well as manage voicemails.
OnSip comes with a queue dashboard, which lets supervisors view, distribute, and track all calls based on multiple status filters such as waiting, on call, abandoned, completed and more. Administrators can set up groups for different teams including sales, support, and billing, which streamlines communications by allowing any user from a team to answer incoming calls and queries. Besides, managers and leaders can generate reports to gain insights into agent performance based on criteria such as maximum wait time, total calls answered, and average duration, among other details.
OnSip comes with an application programming interface (API), which allows businesses to integrate the system with several third-party solutions including Slack, Zendesk, and HubSpot CRM. Plus, users can block contacts, restricting nuisance and unwanted interactions.
Key benefits of using OnSIP
- Unlimited and metered calling plans that are identical to what other VoIP providers offer.
-.The system automatically routes all your calls over a powerful Public Switched Telephone Network (PSTN) to the hosted VoIP PBX system.,
