NoYes. I am facing exactly the same issues you have mentioned.
Another major issue that I am facing is, whenever I call any other landline number from my Jio landline, the phone rings on the other person's side but I don't hear any ring tone on my side.
And when the other person picks the call, the call disconnects (beeping on both sides).
I am able to receive calls from landline numbers but the connection is not very clear. Most of the times, I hear my voice back.
The connection to other mobile numbers from Jio landline is much better.
Do you face this above issue? @SG_curiosity
