Hello,
I'm trying to use Kamailio as a customer facing SBC to handle NAT traversal and basic SBC functionality for a group of backend FreeSWITCH servers. What I'm trying to accomplish is this:
- UAC sends REGISTER
- Auth is handled by the edge proxy, backend server trusts edge proxy
- If NAT is detected, expires is decreased to 60 seconds, proxy sends options ping
- REGISTER is cached and forwarded upstream with Path header and longer expires, i.e. 3600 seconds
- UAC reregisters every < 60 seconds but upstream registration is only changed if the timer expires (just less than 3600 seconds) or if AoR changes
I good illustration is here:
http://www.markholloway.com/blog/?p=1826
My thought is to use htable to store the AoR with an expires just less than 3600, and check it before crafting a new REGISTER with uac module. Is there a better way of handling this scenario?
Is there an efficient way populate the $uac_req(…) pseudo variables and call uac_req_send() for multiple, i.e. 4-6 backend servers? I guess all I would need to change is the RURI?
Thanks,
Spencer
Hi ,
I'm trying to use the db_text and avpops modules to implement a simple custom database but having problems getting it to work .
I'm trying to find the Identity of the recipient for an inbound call based on the called number . I have a database file:-
1) LineIDs - contains the called numbers in the username field and an attribute for that line ID (inbound/ outbound) ,and the recipient identity in the value field
I am trying to get the attribute and value pairs that matches the line number in the user name column ,
id(int,auto) uuid(str,null) username(str) domain(str,null) attribute(str) type(int) value(str)
1::+12125551212::inbound:0:Foster
2::012125551212::inbound:0:Foster
3::12125551212::inbound:0:Foster
4::+4412125551212::inbound:0:Foster
5::+12125551213::inbound:0:Foster
6::012125551213::inbound:0:Foster
7::013440001::inbound:0:Foster
8::call-centre::inbound:0:MBA
9::call-centre::outbound:0:MBA
10::01344665544::inbound:0:chicken
11::01344665544::outbound:0:chicken
I try to load the AVPs that match a received number using the following line in the kamailio script file
$var(rc)=avp_db_load("01344665544/username","s:recipient/LineIDs");
I have also tried
$var(rc)=avp_db_load("01344665544/username","$avp(s:tenants)/LineIDs");
And
$var(rc)=avp_db_load("01344665544","$avp(i:123)/LineIDs");
But it fails to find any matching rows ( AVPS) . Am I using the function correctly ?
The debug output is shown below , there are some custom debug lines I have added in the db_text C files .

Hi!
I have an up and running msilo config with kamailio 4.0.4.
However, all the queued messages are delivered with a prefix "[Offline message - (date)(time)]".
Non queued messages are delivered unchanged.
Is there a way I can remove this prefix, so also queued messages get delivered unchanged?
Please advise!
Any help is appreciated!
Thanks you,
Marc
Hi all,
I'm trying to use rtpproxy-ng module (kamailio 4.1 from GIT) and
mediaproxy-ng (from https://github.com/sipwise/mediaproxy-ng) in
bridge ipv4-ipv6 mode with new NG protocol but keep getting "Failed to
extract streams from SDP: No address info found for stream" (log is
bellow).
Same setup, same SIP clients, same network but with old rtpproxy
module and mediaproxy-ng without NG protocol works fine for ipv4-ipv6
bridge mode. of course, only change is in Kamailio configuration where
now I load rtpproxy module and change sockets not to use new NG
protocol. mediaproxy-ng configuration is untouched.
Best regards
/Pavel

Nov 11 15:58:00 kamailio2 mediaproxy-ng[4790]: Returning to SIP proxy:
d6:result5:error12:error-reason28:Incomplete SDP specificatione
Hi list,
I have this structure
IP Phones -> Asterisk Client (LAN) -> (router) ->
Kamailio/RTPproxy(Internet) -> Asterisk (local from Kamailio) -> Trunk
SIP/Pstn
All is working well, I don't have problems with NAT and I managed about
6000 daily calls.
For a couple of months I've the next problem.The problem is that in the
Asterisk randomly received this message.
[Sep 29 04:04:29] NOTICE[3393] chan_sip.c: Peer 'kamONOp' is now Lagged.
(2075ms / 2000ms)
[Sep 29 04:04:41] NOTICE[3393] chan_sip.c: Peer 'kamailioONO' is now
Reachable. (1888ms / 2000ms)
In some Asterisk Client I get this message 10 times in a hour, and usually
coincide with periods of high load on the kamailo.
Also I am getting these messages in the log of Kamailio:
Nov 11 08:59:53 c1 /usr/local/sbin/kamailio[8079]: INFO: <core>
[forward.c:788]: broken reply to forward - no 2nd via
Nov 11 08:59:53 c1 /usr/local/sbin/kamailio[8082]: INFO: <core>
[forward.c:788]: broken reply to forward - no 2nd via
Are these two issues related?
Whay can I do?
Kind Regards

Hi,
I am new to this mailing list and evaluating various options for a good

algorithms (Ex: weighted and round robin) together for load balancing.

I have a pcap trace that shows all the calls from 3 hours prior and this is
the first time this device appeared.
I followed the code down to the sca_hash_table_slot_kv_delete_unsafe
()routine and it appears to have crashed when it tried to use
e->free_entry which seems to have been NULL at that point. I'm not sure
how it could be NULL since it should have been initialized in
sca_hash_table_slot_kv_insert_unsafe
(). I'm guessing that either e->free_entry was never initialized or
somehow it was overwritten. Since several backtraces end in the same way
the bug seems to have be specific to some sequence of events I have not
been able to identify.
Any help tracking this down would be appreciated.
Thanks,
Bob
Hello,
I would like to know how to uninstall Kamailio. I will be upgrading from 3.0 to 3.3 and I would like to uninstall 3.0. I know that there is an upgrade procedure, but 3.0 now does not work and I would like to start from scratch.
thanks,
I am new to Kamailio and am having an issue with the dialplan setup. I have Kamailio setup as an SBC to handle all user authentication and call routing. I need freeswitch to handle all conferences and voicemails. When I dial 433001 I would like to be transferred to freeswitch for conferences. Right now I have followed the following article and it when I dial 433001 call hangs up and never reaches FS. If I call 43 call does reach FS and I am able to hear FS play the VM prompt.
My system is CentoOS 6.4 and FS is installed via yum, but Kamailio is complied. Both FS and Kamailio are on the same box.
What commands would you suggest I use to troubleshoot these issues in the future.
http://kb.asipto.com/freeswitch:kamailio-3.0.x-freeswitch-1.0.6d-ms#dokuwik…
Also, since I am new could you give some pointers as far as security and documentation.
thanks,
Hi, all
We have applied the openssl 1.0.1e patch described in the email chain
between Roberto Fichera and Daniel-Constantin Mierla back in August. But
Kamailio 4.0.4 still fails to start up and the log shows memory allocation
problem. By the way, we're running kamailio on RHEL 6.5. Wonder if we have
missed anything. Please advise. Thanks.
Ding
