Hello,
probably you want the next snippet:
if (!t_relay())
xlog("L_INFO","Cannot relay PUSHED invite.");
sl_reply_error();
to be:
if (!t_relay()) {
xlog("L_INFO","Cannot relay PUSHED invite.");
sl_reply_error();
}
Because you don't have curly braces for the IF block, only the xlog is
executed in case of error. sl_reply_error() is executed always.
Cheers,
Daniel

Greetings.
We build specialized softphone for iOS. Push notifications are used to
notify user and wake up softphone app on missed calls and messages.
We used Daniel's example config script as base for own configuration
file. It has the same parts and does not differ too much. I talk about
this example:
http://www.kamailio.org/events/2014-KamailioWorld/day2/26-Daniel-Constantin…
Everything was ok for few monthes - with kamailio 4.1.2.
Few weeks ago we upgraded to 4.3.3.
Now paused calls cannot be resumed properly.
Softphone receives 500 Server error (No error 0/SL) in response
This is problem part of script:
route[RELAYRESUMED] {
# enable additional event routes for forwarded requests
# - serial forking, RTP relaying handling, a.s.o.
if (is_method("INVITE|SUBSCRIBE")) {
t_on_branch("MANAGE_BRANCH");
t_on_reply("MANAGE_REPLY");
}
if (is_method("INVITE")) {
t_on_failure("MANAGE_FAILURE");
}
if ($var(rr_target) != "")
{
xlog("L_INFO","Relay to
$var(rr_ip):$var(rr_port)\n");
$ru = "sip:" + $rU + "@" + $var(rr_ip) +
":" +
$var(rr_port) + ";transport=" + $var(rr_proto);
xlog("L_INFO","Current request URI is $ru\n");
if (!t_relay())
xlog("L_INFO","Cannot relay PUSHED
invite.");
sl_reply_error();
}
else
{
xlog("L_WARN","Target proto is not set\n");
sl_reply_error();
}
exit;
}
It produces log

sl_reply_error() sends 500 with No error (0/SL) description. Later 180
& 200 are sent.
But client softphone terminates transaction already (as it handles 500
response code) .
There is no "Cannot relay PUSHED invite." message in the log however.
I will be happy to heary any idea what can be cause...
Thank you!
