[Asterisk-Users] T1 E&M false busy after dial

[jltaylor]

If Feature Group B signaling is working properly (and you have Feature Group
B trunks), then
to reach your Asterisk box you would dial from the PSTN (1)+950+WXXX {W is 1
or 0 based on the number assigned to you}.

If you are dialing "out" {terminating where you look like the carrier} on
FGB then it depends on if you are connected to an Equal Access End Office or
a Access Tandem.

Are you sure about the Feature Group B thing or do you have trunks that just
require MF signaling?

If you want MF, you might try the "featdmf" setting, however, the telco
needs to know that you want FGD.
AND...
If you are connecting to an Access Tandem instead of and End Office, then
the "featdmf" in Asterisk will not work.
I have submitted a request for a quote to Digium to modify the code to make
this work properly.

Likewise, true FGB "terminating" (where it looks like you are the carrier)
works through an Access Tandem and the additional code is missing for that
also.

Take out the featb and add:
em_w

This will let you see if just plain old DTMF works.
