Log:
When a session timer expires during a T.38 call, re-invite with correct SDP

When a session timer expires during a dialog that has re-negotiated to T.38
and Asterisk is the refresher, Asterisk will send a re-INVITE with an SDP
containing audio media only. This causes some hilarity with the poor fax
session under weigh.

This patch corrects that by sending T.38 parameters if we are in the middle of
a T.38 session.

(closes issue ASTERISK-21232)
