What Asterisk version do you have?

The real problem is the other end is not responding to the Seize signal and
openr2 times out. However, in some Asterisk versions there use to be a
problem where the line would stay seized and not return to idle after this
timeout. I remember fixing that problem long time ago, so I need to see
your openr2 and Asterisk versions.
