Inviting a number to a Conference by selecting a conference button and then typing a number in the dial box and hitting enter doesn't work for me. I do that, but nothing happens.
FOP2 doesn't originate a call to the number typed and won't place that call inside the conference selected.

What can I do?

mysql -u root -p asterisk -e "update fop2buttons set context='from-internal' where context='ext-meetme'"

This is what the manual says, but I can't get it to work.
"Invite any number to a Conference : If you select a conference button and then type a number in the dial box and hit enter, FOP2 will originate a call to the number typed and it will place that call inside the conference selected."

I select my conference button, then type a number in the dialpad, hit enter, but nothing happens.

Fop2 debug capture attached.

Looks like the screenshot was cut off at the right end.
Is the command missing a quotation mark or more maybe?
msql -u root - p asterisk -e "up

Thanks a lot, that fixed it.
