Hi 侯旭光,
ok.. Have you tried if its work with an simple example?
kamctl exec "show databases"

Hello,
I will be visiting the first day of UC Expo in London
(http://www.ucexpo.co.uk/), Tuesday, March 8. If you are going to be
there and want to meet for a chat about Kamailio & VoIP, drop me an email.
Cheers,

Hi jack：
I got the same problem with you.
I know little about apache and HTML, would you tell me how to configuration apache specific.
Thanks a lot.

I'm trying to route failed calls to a voicemail URI. The failure route
couldn't be simpler:
failure_route[FAIL_ONE] {
if (t_is_canceled()) {
exit;
}
if( t_check_status("486|408") {
append_branch( "sip:foo@2.2.2.2");
t_relay();
}
}
But, it doesn't work. For example, let's say the initial INVITE
resolves to a local device "me(a)1.1.1.1". This works fine, and the
phone rings. After a timeout, the failure_route executes. The branch
"foo(a)2.2.2.2" gets appended, and kamailio sends a new INVITE, but
instead of determining the correct proxy for the new address, it sends
the INVITE, with the new URI, to the device that original received the
INVITE, "me(a)1.1.1.1". Obviously, this doesn't work.
I've been able to force kamailio to route the call correctly by
modifying failure_route[ to use t_relay_to_udp() as follows:
failure_route[FAIL_ONE] {
if (t_is_canceled()) {
exit;
}
if( t_check_status("486|408") {
append_branch( "sip:foo@2.2.2.2");
t_relay_to_udp( "2.2.2.2", "5060");
}
}
But, it seems like kamailio should figure what where to send the new
INVITE itself. What am I doing wrong?

Hi,
Have following issue:
Alice calling Bob.
Bob make call transfer to Charlie (works fine)
Charlie transfer Alice to David. (the call break)
Why is not possible to transfer the call more than one time?
Is it any parameters?
My ITSP use SER together with Cisco MGW.

Hi,
I installed a kamailio from the debian repository, i use the default
configuration.
The only enable the tcp and tls transport modes, and configured mysql login.
Everyting seems to be working fine.
I would need now to configure rtprpoxy, but i just cant make it work.
My goal is to force rtpproxy for all calls.
Any help is highly appreciated!!
Thank you
Marc
Rtpproxy is installed and seems to be running:
This is my rtpproxy configuration:
------------
# Defaults for rtpproxy
# The control socket.
#CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock"
# To listen on an UDP socket, uncomment this line:
CONTROL_SOCK=udp:127.0.0.1:22222
LISTEN_ADDR=[external_ip]
# Additional options that are passed to the daemon.
EXTRA_OPTS="-l ${LISTEN_ADDR}"
/usr/sbin#
-------------
It seems to be running:
-----------
/etc/init.d# ./rtpproxy start
Starting RTP relay: rtpproxy.
/etc/init.d# netstat -an|grep 22222
udp 0 0 127.0.0.1:22222 0.0.0.0:*

Hi,
I configure the Kamailio 3.1.2 with postgres but I cann't start. In the log
file is generated the following error:
**
ERROR: load_module: could not open module
</home2/local/kamailio/lib/kamailio/modules/db_
postgres.so>: /home2/local/kamailio/lib/kamailio/modules/db_postgres.so:
undefined symbol: PQdescribePrepared
Why this error is generated?
Best Regards
