Video conferencing

OnSIP offers the ability to host free, multi-party video conference calls right within the app. Users can create a video conference room with five users or external contacts. Non-OnSIP app users can click on a unique video conference link to join via a browser window, with no downloads or plugins required.


An auto-attendant menu is a pre-recorded greeting that answers the business’s inbound calls and provides callers with a list of actionable menu prompts. These prompts typically direct callers to a company’s sales team, support department, and billing representatives.

Businesses can also configure a prompt to send callers to a recording that informs them of the business’s hours of operation, physical location, or driving directions.

ACD queues

The system automatically distributes calls to sales or support representatives and has a waiting room for overflow callers. ACD queues (Automatic Call Distribution) let customer support teams handle calls one at a time while new callers wait in line for the next available agent. This feature empowers representatives to deal with each incoming call without losing other callers to busy signals or unanswered phones.

OnSIP Call Assistant for Google Chrome

OnSIP Call Assistant is a Chrome extension that allows users to call phone numbers or SIP addresses within their browsers. This plugin will also notify users of incoming calls with real-time pop-ups containing caller-ID information. OnSIP Call Assistant locates telephone numbers on web pages and converts them to Click-to-Call links on the fly.
