Open for Cisco Webex

Webex Calling remains the phone system. Users, devices (Cisco IP phones, headsets, Webex app), dial plans, hunt groups, and the Webex Control Hub all stay where they are. Open joins as a SIP destination on the side of your phone system that already speaks SIP — typically a Local Gateway (LGW) or a registered trunk to a third-party PSTN provider.

For Webex Calling with Local Gateway, the cleanest pattern is to add Open as a SIP destination reachable through the LGW. Inbound calls hit Webex, follow your hunt group / call queue / auto attendant routing, and at the point you'd hand off to an external endpoint you send the leg to Open over SIP. The AI picks up and the conversation runs over standard SIP/RTP.

For Webex Contact Center, the pattern is even more direct: Open is configured as an external routing destination on a queue or skill. Inbound calls matching the routing condition hand off to Open, the AI handles the conversation, and escalations transfer back into a Webex Contact Center queue via SIP REFER with the live transcript and detected intent attached.

What the AI does on the call: it listens, reasons over your knowledge base and connected tools (Salesforce, HubSpot, Zendesk, ServiceNow, calendar, payments), and acts. Every call is recorded and trace-logged on Open's side; on Webex's side the call leg appears in Control Hub analytics like any other SIP call.

Billing stays predictable. Cisco keeps invoicing your Webex seats and any Cisco-supplied calling plans. Open charges per resolved conversation, with no markup on Webex minutes and no extra Webex seats needed for an AI front-line.
