Hello @Marco Navarro yes you can enable inbound telephony calling for Azure Communication Services. This allows users to join a video call by dialing a phone number. The Call Automation SDK helps manage incoming calls to phone numbers acquired from Communication Services or via direct routing
By integrating PSTN capabilities with your video call setup, you can allow participants to join the video call via a phone call. This is particularly useful for users who may not have access to a stable internet connection or prefer to join via phone
Hope that helps
