[asterisk-users] Grandstream FXS Gateway star codes

[Yu Safin]

I purchased a Grandstream 4 FXS Gateway and my *XXXX extensions are
not working.   I disable the special features and changed the DIAL to
{X*#+} but not luck.
I can dial any other number, receive calls and so on.   This is the
only thing that seems to be an issue.
Has anybody found a way around this problem.
