A pound to a penny that the 290.... number has the word "softphone" close to it. Every account on
obitalk.com is allocated a softphone number. It is not the number of your OBi200 and you can ignore it.
The warning about OBi100/110 being End-of-Life appears on everyone's dashboard. Again you can ignore that.
Until you can dial **9 222 222 222 and hear "Welcome to Obitalk ...." you will make no progress. What does happen when you dial that number? Do you hear dial tone when you take the phone off-hook? Does it go away when you start to dial? OBis do not support pulse dialling. You must use a phone that tone dials. If yours can do both check that it is set to tone.
Also it is not wise to publicise your 9 digit numbers. You may wish to modify your post.
