No, if connect or send fails you'll have to rely on tm timeouts.
If the connect or send fails immediately (never seen in practice but
theoretically possible), it behaves like the old tcp.

BTW: I don't think that for immediate errors (like send failing in
kamailio tcp) one should call the failure route. You can always detect this
using something like if (t_relay())... and you have more control this way.
