Hi Matt,
Just to clear things now, when I dial the EXT manually from my station and then redial the same EXT it is passing successfully.
The problem that when I recieve a call or a missed call and then try to redial the EXT it is showing the EXT with 9 as prefix.
This is the trace ... My EXT is 1101 .. I called it from EXT 6666

Now I redialed 6666 from 1101 and this is the results:

And for my troubleshooting today I found a telephone that is not facing this issue, it is the same as mine 9620 ...
Please advise me if you want anything else...
