Hi, This is Elias from Miami. From the information provided, it seems you're experiencing an issue with no audio during incoming calls on your existing VOIP app. With over 10 years of experience in this field, I'm very interested in this project as I'm highly familiar with the pjsip library Additionally, I have a few questions regarding your project 1. Has the issue started after a specific update? If so, what changes were made in that update? 2. Are both the microphone (input audio) and speaker (output audio) affected, or is it one-sided? 3. Are there any recent changes in SIP account or server configurations (e.g. codecs, NAT settings, RTP ports)? 4. Does the app use CallKit for call handling? If so, are there any issues with the CallKit integration? Looking forward to hearing from you. Regards.
