^^^^^^ the avp timers are in seconds, so you shouldset them it to 3. All the other timeouts are in ms (I'll add a note to the docs).
i did so, but it didn't affect the error messages. while doing it i noticed that fr_timer is not very accurate. i call next_gw() when previous call times out and syslog reports 5 second intervals:

An avp always has a value if it exists. If its value is the empty string or 0 => the avp integer value will be 0 => in this case the timer will be set to 0.
i added xlog statement before first next_gw() call and it reports that fr_inv_timer_avp has value null:
Jun 22 17:56:46 localhost /usr/sbin/sip-router[5881]: INFO: fr_inv_timer_avp <null>
I'll add a check for 0 in sr too (so that it will be compatible with the k way).
that would be nice so that script writer can leave the avp unset if there is no need to change the default set by the module parameter variable.
Note that in ser the modern way to use avps for timers is via t_set_fr() & friends (you can set everything from fr timers to retransmission and lifetime, you can later reset to default via t_reset_fr() and you can use it only when needed).
thanks for the pointer. i'll take a look at those.
