Hi guys We currently use Issabel as our PBX and a physical gateway with Movistar SIM cards, where Issabel connects to the gateway via a SIP trunk to convert VoIP calls to GSM. Traditionally, for outbound calls, an agent answers through a softphone. However, we now want customers to interact directly with VAPI during the call (for example, to listen to real-time voice messages or navigate through automated menus). Given this outbound call scenario, my questions are: What is the best way to integrate VAPI so that customers can interact directly with it during an outbound call? Do you recommend connecting VAPI via SIP to Issabel (as a SIP endpoint or via the dialplan) to intervene in the call, or is there a more direct integration option with the gateway? I am not sure if this is the correct approach to implement VAPI in this case, or where exactly VAPI should be positioned in this scenario. any info is helpfull. here are some specifications: - CNT SIP Trunk: This is a SIP connection provided by CNT. It is used to handle specific types of calls (such as fixed or international calls) or to serve as a backup route. In the current flow, it acts as an alternative depending on the configuration and route availability. - Gateway: This is a physical device that serves as a bridge between Issabel and the cellular network. It receives calls via a SIP trunk from Issabel and converts them into GSM calls, enabling connection to the mobile network. - Movistar SIM Chips: These are the SIM cards installed in the gateway. They allow the device to make calls using the Movistar network by converting VoIP calls into mobile calls to reach the customer’s cell phone. Note: I have reviewed the documentation regarding BYO and SIP for outbound calls, but I’m not entirely sure if this is the correct approach. The goal is to have VAPI replace human agents for outbound calls, allowing customers to interact directly with VAPI. Thank you! For any help
