It works now.
I think the T1 is fine, I am running it on 4ESS. Verizon told me they
are running at 4ESS. I use isdiag tool following this link:
http://threebit.net/projects/jvr/current/doc/html/
At the very bottom, it showed how to make a outgoing call. I followed
the steps, and it worked in isdiag. Looks like we can not use the
default setting all the time.
I am trying to make it work in code.
