Hi @William_67134 thanks for reaching out to us here on 3Community.
Did you know that you can extend your ringing time through your phone? All you need to do is **61* _____ **no.of seconds(5-30)# and call. So if your number was 0861234567 you'd type **61**08651234567**30# and then press the call button.
Please let me know if you've tried this and still need assistance.
