RTPProxy with kamailio : How to get calls count?

by Mino Haluz

Hi, I'm doing the performance test with kamailio + RTPProxy, but I would like to get the real calls count that the rtpproxy is serving. I don't want to use value that I get from sipp. So is there any management tool for rtpproxy, or should I get it somewhere in kamailio config ? Thanks, Mino

script stops processing when relaying e2e ack?

by Andrew Mortensen

Hi all. I'm working on a custom module and would like to be able to send UPDATEs to the call legs after the script forwards the e2e ACK from the caller. I had hoped to export a function to call in my ACK handling route after the script forwards the ACK. However, the script stops processing after calling t_relay in my ACK handling route. I tracked this back to the fact that t_relay_to invokes forward_request when handling e2e ACKs, and returns the return code of forward_request to the script. Since forward_request returns 0 on success, the t_relay call in the script returns 0, which stops script processing. Is this intentional? My module currently hooks the TMCB_E2EACK_IN, and I can UPDATE the caller here, but the callee seems to be ignoring the UPDATE if it's received prior to the ACK. Thanks for any advice you can offer. andrew

Kamailio 3.2, NAT, rtpproxy bridging between interfaces

by Russell McConnachie

Hello, I'm having some issues getting media bridging working in kamailio and rtpproxy. I've attempted to attach as much relevant information as possible. Thanks in advance for taking a look; I'm completely stuck right now. Actual results:No audio is being passed through the rtpproxy from caller "A" to caller "B" even though both media server and UAC are sending media to the rtpproxy. Expected results:Audio that is sent to rtpproxy is bridged/proxied across from caller "A" to caller "B" and vice-versa. -------------------------------------------------------------------------------

Max-Forwards: and loops. Testing purpose.

by Anton Kvashenkin

Hi, List. I'm using sipsak to fire some predefined sip message with Max-Forwards: header equal 0 to test mf_process_maxfwd_header function. I'm doing this exclusively for learning purpose. As far as we know, this exported function from maxfwd module services only for adding Max-Forwards header, decrement or detect Max-Forwards: 0 header to prevent loops. So, my question guys, how can I create this loop in my lab, with two proxies for example? What message should I craft?

using kamailio with clients in a nat environment

by David Thomson

hi, I was wondering if in clients in a nat environment need to be in the dmz or need to have ports forwarded for kamailio to be used to connect the clients? I have setup kamailio with the nat settings but am still only getting one way audio. chances are it has not been setup correctly but just checking. If i try to connect the two clients from the same network i can get zrtp and 2 way communication working correctly. if one of the clients is on a different network the call initiates and answers but zrtp and 2way audio does not work. kamailio 3.3 running on ec2 ttyl,Dave

Re: [SR-Users] Jurisdictional (inter vs intra calling) LCR on Kamailio

by Alex Balashov

William, This is a business-layer function that is far outside the scope of what built-in Kamailio modules can do. In fact, even the 'lcr' module is something of a misnomer: it does not do LCR in a truly financialised sense, to say nothing of jurisdictionally specific regulatory awareness. It's just a basic weighted routing table. The appropriate place to find such functionality, unless you want to write it yourself, is in a variety of ITSP-oriented commercial platforms built on top of Kamailio. They exist precisely to fill these gaps and bring the somewhat general capabilities of Kamailio into an applied dimension that is useful in specific business and product contexts. Many members of this list represent software or consulting companies that offer such solutions. However, as it is a noncommercial list, I'll refrain from plugging them directly. You may want to ask the question on Kamailio-Business. You can also email me privately and I would be happy to give you some unbiased pointers about the commercial ecosystem. -- Alex -- Sent from my Samsung mobile, and thus lacking in the refinement one might expect from a proper keyboard.

Jurisdictional (inter vs intra calling) LCR on Kamailio

by William Fulton

I can't find any information anywhere on how to get jurisdictional lcr configured. I have intra and interstate rates for each carrier rate deck and don't know how to let the system know when one is appropriate versus the other. Can someone point me to a tutorial or some documentation on this? Thanks so much! William

rls notify delay

by Juha Heinanen

one rls thing that stilll wonders me is the about 2-5 sec delay that occurs when backend notifies have been received and notify to subscriber ua is sent: Sep 11 17:27:41 siika /usr/sbin/sip-proxy[4495]: INFO: Routing PUBLISH <sip:foo@test.fi> to presence server Sep 11 17:27:41 siika /usr/sbin/pres-serv[19270]: INFO: Handling PUBLISH <sip:foo@test.fi> Sep 11 17:27:41 siika /usr/sbin/pres-serv[19270]: INFO: Routing locally generated NOTIFY <sip:rls@127.0.0.1:5082;transport=tcp> to <sip:jh@test.fi> from <sip:foo@test.fi> Sep 11 17:27:41 siika /usr/sbin/pres-serv[19270]: INFO: presence [notify.c:1575]: NOTIFY sip:jh@test.fi via sip:rls@127.0.0.1:5082;transport=tcp on behalf of sip:foo@test.fi for event presence Sep 11 17:27:41 siika /usr/sbin/pres-serv[19271]: INFO: Handling in-dialog NOTIFY <sip:rls@127.0.0.1:5082;transport=tcp> from <sip:foo@test.fi> to <sip:jh@test.fi> Sep 11 17:27:46 siika /usr/sbin/pres-serv[19265]: INFO: Routing locally generated NOTIFY <sip:cyvrphbz@192.98.103.1:60122;alias=192.98.103.1~47419~2;transport=tcp> to <sip:jh@test.fi> from <sip:jh-buddies@test.fi> Sep 11 17:27:46 siika /usr/sbin/sip-proxy[4482]: INFO: Routing in-dialog NOTIFY <sip:cyvrphbz@192.98.103.1:60122;transport=tcp> from <sip:jh-buddies@test.fi> to <sip:192.98.103.1:47419;transport=tcp> this does not depend on the pua patch nor which db_mode i have in rls module. -- juha

rls does not generally work

by Juha Heinanen

it turned out that presence rls module does not work unless pua module is configured to use database mode and database is postgre. the issue is serious, since besides not working, it makes presence/rls server not to accept any new requests. since there is no easy cure, should i go and write a warning in rls readme file so that others don't stumble on this? -- juha

siptrace and homer

by Krishna Kurapati

Hi, We have been using homer for some time. The logging is stopping once the disk is full, which make sense. However, it would nice if either kamailio or homer has an option to auto-truncate the siptrace database tables once they grow large. Is there such a feature? Regards. Krishn Kura
