Hello Team, We have developed an SIP Client application, where the connection is through SIP Server. We are unable to handle incoming calls when app is in the background. The local servers are blocked by firewall due to which the push notification is unavailable and is only available via VPN connection. Requesting you to please guide us on how we can receive incoming calls without push notification. We also would like to know how we can receive incoming calls when the app is completely terminated or closed from background and how to auto-start the app to receive incoming calls.
