[SR-Users] Error in syslog: BUG tm [t_msgbuilder.c:351]: unhandled reason cause -18344

[Mikko Lehto]

Hi

I am testing certain UAC behavior on proxy initiated 408 response with 
SIP Router. Call canceling is working fine - UAC gets 408 and GW gets 
CANCEL.

However this error message is seen in syslog after fr_inv_timeout fires:
BUG: tm [t_msgbuilder.c:351]: unhandled reason cause -18344

In script I set t_set_fr before t_relay, otherwise it is default:
route[RELAY] {
   if (is_method("INVITE")) {
     t_on_reply("REPLY_ONE");
     t_on_failure("FAIL_TEST");
   }
   t_set_fr(4000);
   if (!t_relay()) {
     sl_reply_error();
   }
   exit;
}

SIP Router is self compiled from Git:
sip-router 3.1.0 (i386/linux) 34d2f6

Here are TM parameters:
#modparam("tm", "local_cancel_reason", "0")
modparam("tm", "noisy_ctimer", 1)
modparam("tm", "auto_inv_100_reason", "tryink")
modparam("tm", "failure_reply_mode", 3)
modparam("tm", "fr_timer", 30000)
modparam("tm", "fr_inv_timer", 120000)

The above error message is found in t_msgbuilder.c on
#ifdef CANCEL_REASON_SUPPORT -block.
Looks like I do not have compiled in support for that new feature as I 
get error when uncommenting local_cancel_reason tm parameter:
ERROR: <core> [modparam.c:150]: set_mod_param_regex: parameter 
<local_cancel_reason> not found in module <tm>

Is this bug as log message suggests?
