Designed with efficiency and campaign optimization in mind, this new report empowers users with deeper insights into the status of their calling campaigns. Along with this powerful new report, the latest release of SIP Caller also brings support for Portuguese, French, and Polish languages, making our platform even more accessible to users worldwide.
The Number Details Report is a comprehensive tool that gives you full visibility into the performance of your SIP Caller campaigns. With this report, you can:

Black lists and contact lists can now be fully managed through the SIP Caller REST API. You can create, edit, and delete lists, and add or remove their numbers and variable values, directly from your own systems. A new endpoint also loads every number from a contact list into a campaign with a single request. Keep opt-outs in sync with your CRM, refresh contact lists on a schedule, and provision new accounts end-to-end without a single manual step in the console.

This release brings three meaningful improvements to SIP Caller. The list of campaigns in the Dashboard, Campaigns menu, and Reports menu now shows a detailed status icon explaining exactly why an active campaign isn't making calls. Campaigns can now also be assigned a Priority (High, Normal, or Low), so your most important campaigns get access to calling capacity first. And thanks to internal architectural improvements, campaigns now start making calls within 5 seconds of activation, down from up to 30 seconds previously.

OpenAI and Grok are now available as AI Providers in SIP Caller, joining our existing support for Microsoft Azure AI and Google Gemini AI. Both new providers can power AI Conversational Agents and AI-Based Voicemail Detection across your outbound campaigns. With four AI providers to choose from, you can align SIP Caller with the AI provider agreements your company already relies on elsewhere, or simply pick the best option available on the market for your use case.
