This is pretty strange, since it never happened to me on an AMD
machine, though i have different model, AMD Athlon II X2 250e. 

Can you
try using fr_timer_avp? e.g. 

modparam("tm", "fr_timer_avp",
modparam("tm", "fr_inv_timer_avp", "$avp(20)") 

See more

http://www.opensips.org/html/docs/modules/1.10.x/tm.html#id293753 [3]

Set these vars and print xlog when INVITE comes in. 

branch_route {


 $avp(10) = 5; 
 $avp(20) = 60; 
"[$pr:$fU@$si:$sp]: Setting TRY timer to '$avp(10)' and RING timer to
'$avp(20)' for call from '$fu' to '$ru' n"); 

Then check in
failure route, 

failure_route { 

 if (t_check_status("408")) { 

if ( t_local_replied("all") ) { 
 # local timeout with no reply received
-> fr_timer 
 xlog("L_NOTICE", "[$pr:$fU@$si:$sp]: Timeout on TRY timer
for '$rm' from '$fu' to '$ru' after '$avp(10)' seconds n"); 
 } else if
( t_local_replied("last") ) { 
 # timeout with replies received ->
 xlog("L_NOTICE", "[$pr:$fU@$si:$sp]: Timeout on RING
timer for '$rm' from '$fu' to '$ru' after '$avp(20)' seconds n"); 
else { 
 # received timeout 
 xlog("L_NOTICE", "[$pr:$fU@$si:$sp]:
Timeout on T2 timer for '$rm' from '$fu' to '$ru' after '$avp(20)'
seconds n"); 

This will make things clearer if there
is any problem. 

Thank you.

servers, sometimes timeout happens after 6, 9, 12 seconds but never (so
far after) 5 seconds. But in other machines, fr_timer is consistently
respected. So I am trying to figure out what would be causing this. 
Does anyone have any idea of configuration of the server that could
cause this?
