We’re excited to announce two new SIP Caller improvements that, while seemingly small, make a big difference in day-to-day workflows. These updates are designed to help you work faster, reduce manual steps, and get more value from your existing campaigns.
Until now, duplicating a campaign in SIP Caller was an all-or-nothing choice:
That worked, but it often meant extra cleanup or manual filtering afterward.
You can now duplicate a campaign and choose exactly which numbers to include, based on their status in the original campaign.
When duplicating a campaign, you can select filters such as:
This allows you to quickly create a new campaign based on a previous run—without exporting lists, re-uploading files, or manually adjusting data.
This improvement is especially useful when:
In short, it turns past campaigns into reusable building blocks.
We’ve also enhanced blacklists by allowing you to add a description to each blacklist entry.
When blacklisting a number, you can now specify why it was added, for example:
Over time, blacklists can grow large, and without context it becomes difficult to understand:
With descriptions, your team gains clarity, traceability, and better compliance control.
Individually, these features may look like minor enhancements. Together, they significantly simplify campaign management and reduce operational friction—especially for teams running high-volume or recurring campaigns.
As always, these updates are available immediately in SIP Caller, and no additional configuration is required.
If you have feedback or ideas for further improvements, we’d love to hear from you.
Happy dialing! 📞

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.
