A 'git grep t38timeout' on the src leads one to res/res_fax.c, where one
case see that it is the number of miliseconds to permit for t38 negotiation
to complete once it starts.

Ie after both sides select t38, until they agree on the t38 terms.

OK, so does that mean that setting it to 25000 should leave time for the
re-invite or does the timeout start after that.  If so is there another
control for waiting for the re-invite?

Note, a test by my provider shows that this particular number gives the
re-invite after 6 seconds.  I hang up at 4.

As I wrote above, after that.  After the sip/sdp.
