Yes, that is the default.

You should use
SIPTAG_REQUIRE_STR("timer, 100rel"),
NUTAG_SESSION_TIMER(3600)
> Also, would I only specify these when calling nua_invite()?
That depends. I guess you should set NUTAG_SESSION_TIMER(3600)
nua-wide, but you can use SIPTAG_REQUIRE_STR("timer, 100rel") only
with nua_invite() (and SIPTAG_UNSUPPORTED_STR() only with
nua_respond()). In other words, they are ignored with nua_set_params()
or nua_set_hparams(). I guess that is what you meant that they "do
not work".
A feature tag in Require header implies that it is Supported, but the
feature tags listed with SIPTAG_REQUIRE or SIPTAG_REQUIRE_STR are not
added to the list of Supported features stored in the handle. I guess
this could be considered as a bug and fixed...
