Pay attention to the ⚠️ indicator in the section /forwarding our bot is opposite your number, as soon as at least one forwarded call reaches our servers it will go out. If it is on, it means that forwarding has not yet been enabled by your telecom operator, try turning it off and on again, or using another method of enabling forwarding; it is also important to check the number balance with your telecom operator, since the forwarding service to local numbers is paid (but at times cheaper than roaming calls).
If the indicator goes off, but calls are not going through, check the privacy settings of your account, whether you are allowed to receive calls in principle, also check the balance of the number with your telecom operator, it could have run out.
