There are few issues/bugs and lags with this new Jio landline service.
(1) There is a very long delay/ lag (8 to 15 seconds) in out-going calls after dial any number (mobile or landline of any company).
And sometimes, there is a delay in incoming calls ringing on my landline also.
This delay is very high compared to other companies's landline service like BSNL Landline which is very fast to connect compared to Jio landline.
(2) Jio Landline ringing pattern is not good and also very irritating & unpleasant.
First there is a long continuous ringing of around 15sec and then long pause of 15secs and then again long ringing 15sec. (Same in all landline devices).
This issue is not with my old BSNL landline service.
This is not normal ringing pattern. Jio need to improve the landline ringing pattern. There should be 5sec ringing and then 3sec pause and then again 5sec ringing pattern.
(4) Jio VoIP landline service stop working after when I change the Jio's default
DNS Address to other Public DNS like
Google DNS 8.8.8.8 or Cloudflare DNS 1.1.1.1 and then restart the
router.
Why they provide option/setting in Jio GigaFiber
ONT to change the Jio default DNS to other Public DNS if their system don't support it?
(4). One other thing also which I don't like is that there is no old BSNL landline like Dail-Tone. There is a continuously beeeep sound ( like tuuuuuuuuu..........) when we pick the receiver but not like old BSNL landline dail-tone (like turrrrrrrrrrrr.......) .
This Jio dail-tone should be change to older BSNL copper based landline dial-tone because general public and specially older citizens are more familiar with older dail-tone and not comfortable with this Jio dial-tone.
(2) Sometimes, when I call to other person or when I received a call from other person to my landline, the other person cannot able to hear my voice clearly and sometimes we both cannot able to hear each other's voice. This happens sometimes.
It's a serious issue. Jio VoIP landline service is not fully reliable currently and due to this issue, the customers can't fully trust on the Jio landline service as of now.
