Hi' Carsten,

Of course that t_on_failure is in request route. I think that in kamailio is the problem, because the forward not arrive to SEMS and kamilio log says:

Hi,

did you add a "t_on_failure" in your request route? Your route works for busy subscribers i guess? The problem is likely, that your sip-router box receives a "500 Retry later" from some endpoint (either the device or SEMS) and you have no rule for handling 500-responses:

if (t_check_status("486|408")) {

You only forward to sems here, if your proxy receives a "486 Busy" or a "408 Request timeout", not if it receives any other reply. You should check, from where you receive the 500-reply; it is not generated by the sip-router proxy.

Hi'

I'm trying to forward the call to voicemail on sems when the time of response is out. When the user isn't in location, the forward to voicemail work very fine ( $rc = -1 ). But failure_route, doesn't work and send message "500 Retry Later".

I'm using kamailio 3.0.2 and I'm probing with:

modparam("tm", "fr_timer", 10) modparam("tm", "fr_inv_timer", 15) ... ... failure_route[FAIL_ONE] { #!ifdef WITH_NAT if (is_method("INVITE") && (isbflagset("6") || isflagset(5))) { unforce_rtp_proxy(); } #!endif

   if (t_is_canceled()) {
           exit;
   }

    if (t_check_status("486|408")) {
            revert_uri();
            avp_db_load("$ruri","$avp(s:email_address)/$email_scheme");
            append_hf("P-App-Name: myvoicemail\r\n");
            append_hf("P-App-Param:

Email-Address=$avp(s:email_address)\r\n"); rewritehostport("sems_host:5080"); append_branch(); t_relay(); } }

Thanks.

Hi Carsten,

The problem is solved, but with a litle bug. The calls from qutecom are not relayed to sems. Here is the solution:

failure_route[FAIL_ONE] { #!ifdef WITH_NAT if (is_method("INVITE") && (isbflagset("6") || isflagset(5))) { unforce_rtp_proxy(); } #!endif

if (t_is_canceled()) { exit; }

if (t_check_status("486|408")) { avp_db_load("$ruri","$avp(s:email_address)/$email_scheme"); append_hf("P-App-Name: myvoicemail\r\n"); append_hf("P-App-Param: Email-Address=$avp(s:email_address)\r\n"); append_branch(); fix_nated_sdp("1"); t_relay("sems_host","5080"); } }

Thanks very much Alejandro Mellado

Hi,

from the logs you see, that you proxy actually parses the "500 Try later" reply, so it must have received it.... You should check, from where you receive the 500-error; then you could see, if you want to adapt your config.
