We are excited to announce a powerful new feature in SIP Caller that gives users greater control over how numbers are dialed in their campaigns. Now, you can define the number selection algorithm to be either First In, First Out (FIFO) or Last In, First Out (LIFO).
This feature is particularly valuable for dynamic campaigns, where new numbers are continuously added using our REST API. Depending on your needs, you can now decide whether SIP Caller should prioritize calling the most recently added numbers or follow the traditional approach of calling numbers in the order they were added.
SIP Caller users can easily configure their preferred number selection mode within the campaign settings. It’s also possible to define a preferred default value, so every new campaign is pre-configured with the selected mode. This added flexibility allows businesses to fine-tune their outreach strategy for maximum efficiency.
With this enhancement, SIP Caller continues to evolve as the go-to dialer solution for businesses that need intelligent, automated, and adaptable dialing capabilities.
Try it out today and optimize your campaigns like never before!
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.
