The number stored in Speed Dial 2 is **9 following the Obi number. I tried to call the GV number of this box and then make a new call using OBI network.
Using an example OBi number of 200123456, it should be **9200123456 not 200123456**9.
Yes, this is the format I used. Here is mine: **9200765106.
Now I have just updated firmware to 1.3.0 (Build: 2532) and tried it again,
This time is not getting "invalid" but auto disconnected after saying "please wait while your call being connected". Actually it is not the speed dial problem now. I enter the full number "**9200765106#" and still got discounted. Before it worked that way.
I also checked all following settings using Obitalk settings, I think they are all default since I have not changed anything:
Voice Services -> Auto Attendant -> DigitMap
Voice Services -> Auto Attendant -> OutboundCallRoute
Physical Interfaces -> PHONE Port -> DigitMap
Physical Interfaces -> PHONE Port -> OutboundCallRoute
