Can't make calls out. But can receive calls on land line

[JC1]

My land line has stopped allowing me to make calls but there are no issues receiving them. This happened a week or two ago , previously phone was working fine. I have nbn and that is fine.

Hi JC1

If your NBN service is ok (means the speed is correct and you dont have any issues on browsing).

I may advised you to factory default the TPG modem.

Pressing the pinhole on the back for 10 seconds.

The link below relates to problems connecting to internet. I have no problems connecting. The only issue is being unable to make calls.
