Hi All,
I am trying to send a mi command over the mi_datagram udp socket. I dont
seem to be getting a response back from the server. I am certain that it
is something I am doing wrong.
I have mi_datagram loaded and listening on udp:1.1.1.1:8080.
I then try to send the following dispatcher mi command over to the mi_dg
interface:
echo -ne ":ds_list:\n\n" | nc -w 1 -u 1.1.1.1 8080
I dont see any error in the log file, so it appears that the mi_datagram
is processing the request, but I am not getting any response back.
The ds_list command works properly if I run it using "kamctl fifo
ds_list", or if I go via "sercmd mi_dg ds_list" that works too.
Would anyone have an example bash/ksh/perl snippet that would help me on
my way to communicating with this mi interface.
Any thoughts comments would be greatly appreciated.
Thanks
Hello.
I had a Kamailio version of 3.0.3 and during this time configured a
failover with simple routine. In short like this:
if (ds_next_domain()) {
xlog(.....);
if (!t_relay()) {
xlog(.....);
return;
}
return;
} else {
t_reply("503");
}
Then I've updated to 3.1.3 and was happy enough until I've discovered
that my failover is not working anymore.
What is observed:
- It changes $rd variable, but not changing $du variable, is it ok?
- Not any of the nodes receive packet on t_relay after ds_next_domain().
- In route decision section, where t_on_reply() and t_on_failure() are
located I have the same t_relay() and it works fine, cause there is no
any ds_next_domains().
Is it a bug or I'm doing something wrong?
Thanks in advance.
Hi, summarizing I have two pseudo-variables:
$var(allowed_zones) = 5;
$var(id_zone) = 2;
The binary representation of 5 (3+2), assuming 8 bits lenght, is:
00000101
so bit 0 = 1,
bit 1 = 0,
bit 2 = 1
...
Now I just need to know if bit number 2 ($var(id_zone)) of
$var(allowed_zones) is 0 or 1.
Is there any function like isflagset() but for pseudo-variables?
Thanks a lot.

Hello
not sure what you want to accomplish, but in case it might help this is how
we use the mtree module.
Our 3 columns are: partition, prefix, route
Partition is just a name that defines a group, this is done inside the
script before calling mt_match (via a table lookup for instance). Let's say
if a call comes from ip x we assign it to partition 400; if it comes from ip
y we assign it to partition 401. Each partition is a different tree.
Consider these entries in the tree table:
400,123456,A
401,123456,A
401,1234567,B
Let's say both x and y send a call with $rU 1234567; mt_match will return A
for ip x, and B for ip y; we use that information for taking further routing
decisions. A common situation might be: x has a unique route for a whole
country while y has that entry but has more defined routes for more specific
area codes inside that country. The column route could also be for instance
the setid of a group of gw's for the dispatcher module, etc...

Hi,
I had a setup with an old version where I used the function
t_relay_to("0x02").
Following the 3.1 documentation, flag :
* 0x02* - do not generate reply on internal error (NOTE: has no effect
anymore)
I used that function as a workaround with a pbx that stop to register when
it receive an error response like
478 Unresolvable destination or 408 request timeout.
I did upgrade to 3.1 to have dns srv caching.
Do you know how this would be possible with kamailio 3.1.
Thanks for your suggestions,
hp
In Kamailio 1.4.3
I have the following scenario:
$var(a) = 0
$var(b) = 0
$var(a) = $(tU{s.len});
$var(b) = $var(a) - 5;
xlog(" $var(b)");
the result $var(b) is always the same as $var(a)
should i check if some specific module is loaded?
the debugs does not show any error, and $var(a) and $var(b) are unique.
Variables are working, but not the operations with the variables.

Hi, I'm testing Kamailio's NAPTR resolution:
version: kamailio 3.2.0-dev4 (x86_64/linux)
flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS,
USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM,
SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX,
FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR,
USE_DST_BLACKLIST, HAVE_RESOLV_RES
ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16,
MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB
DNS related configuration:
dns_servers_no=2
dns_srv_lb=yes
dns_try_naptr=yes
dns_use_search_list=no
use_dns_cache=yes
use_dns_failover=yes
dns_tls_preference=1
dns_tcp_preference=1
dns_udp_preference=1
As the doc says it should respect the priorities of the NAPTR records,
see http://kamailio.org/dokuwiki/doku.php/core-cookbook:3.1.x#dns_sctp_pref_dns…:
"To use the remote site preferences set all dns_*_pref to the same
positive value
(e.g. dns_udp_pref=1, dns_tcp_pref=1, dns_tls_pref=1, dns_sctp_pref=1)"
So my kamailio receives an INVITE for an external domain oversip.net
(no transport param neither port in the RURI) and does a t_relay.
Request RURI is sip:qwe@oversip.net.
According to NAPTR:
~$ host -t naptr oversip.netoversip.net has NAPTR record 5 50 "S" "SIPS+D2T" "" _sips._tcp.oversip.net.
oversip.net has NAPTR record 10 50 "S" "SIP+D2T" "" _sip._tcp.oversip.net.
oversip.net has NAPTR record 20 50 "S" "SIP+D2U" "" _sip._udp.oversip.net.
oversip.net has NAPTR record 40 50 "S" "SIP+D2S" "" _sip._sctp.oversip.net.
oversip.net has NAPTR record 50 50 "S" "SIPS+D2S" "" _sips._sctp.oversip.net.
So it should try TLS over TCP first, if it fails try TCP and if it
fails try UDP.
However it just uses UDP, why??
Even if I set a minor value to dns_tls_preference (so higher priority
I expect) it still uses UDP.
Am I doing something wrong? Thanks a lot.

Hi,
does kamailio support conference calls or it has to be implemented in
some B2BUA ?
If it is supported, what are the requirements (modules etc.).
Thanks,
Mino
