Thanks for the response .This behavior is not limited to telegram. It also occurs on Signal app.This i-phone is dual sim .After trying to troubleshoot , I can confirm that - Once we disable E-sim everything works normally as it is suppose to . All calls connect as well just like they are suppose to do. If we enable it , same problems start to arise . Looks like dual sim is confusing communications .

Contact the app vendor, as it appears there’s an issue with the app and dual-SIM configurations.


Signal states that dual SIM (two numbers) is not supported: https://support.signal.org/hc/en-us/articles/360007319251-Dual-Sim
