Following your guide, I've tried several times with the result as below:
1st time, CallerID shown: 31234567
2nd time, CallerID shown: 91234567
3rd time, CallerID shown: 01234567
4th time, CallerID shown: 21234567
I used the same Mobile phone with the same number to call-in, it seems OBi110 generated a random number and add it in the front of the caller number. |
