Issue with 4.2.0 and nathelper and/or rtpproxy
by Igor Potjevlesch 04 Dec '14

04 Dec '14

Hello, Since I done the upgrade of Kamailio into 4.2.0, there are, at least, one new case where the RTPProxy is launched. When I got an INVITE from my PSTN Gateway, for unknown reason (and not for all calls), Record-Route is append with nat=yes. I looked into an old trace and this behaviour didn't exist. What could have changed that can explain this? Regards, Igor.

One way audio calls
by Will Ferrer 03 Dec '14

03 Dec '14

Hi All We are experiencing an odd problem with 1 way audio in about %6-%8 of our calls. It seems to me that what is happening is that our kamailio installation (using rtpengine) is some times ignoring the c= attribute that the carrier is sending us, and sending our audio instead to either address in the carriers o= attribute, or just to the same address we sent our sip invite too. We have looked at hundreds of calls and haven't found a reliable pattern why this happens some times and not others. It really happens in a lot of different scenarios with lots of different carriers and differently formatted SDP packets. I was wondering if any one had an idea where to start for a solution, or a way to make rtpengine always send audio to the ip in the c= attribute we are receiving from the carrier. I haven't been able to find anything so far. Thank you much for any assistance. All the best. Will

Noob hoping for guidance
by john＠millican.us 02 Dec '14

02 Dec '14

Hello, I have been googling for a simple (as simple as it can be knowing the complexity of Kamailio) for a "how to/step bey step/do this dummy" type of guide to get Kamailio registered with a sip provider I already have, and register one end point to kamailio that can use that provider. Nothing fancy or involved just the absolute basics. Does this exist and if so can you please point me to it? Thanks, JohnM

tsilo question
by Klaus Darilion 02 Dec '14

02 Dec '14

Hi! Currently tsilo allows to add branches in failure route or request route (e.g. on REGISTER). would be be possible to allow this function also in reply routes? E.g. if one branch replies with 3xx, to add a new branch to the CFWD target but still have the other branches ringing. regards Klaus

how to access request uri of answering branch?
by Juha Heinanen 02 Dec '14

02 Dec '14

lets say that invite is parallel forked to two contacts. if the call is answered, i would like to set in reply route an accounting avp that contains the request uri of answering branch. i have tried $T_req($ru), but that gives the original request uri. any suggestions? -- juha

Install snmpstats
by Igor Potjevlesch 01 Dec '14

01 Dec '14

Hello, I tried to install the snmpstats module following this process : I installed the dependencies for snmpstats module, then i modified modules.lst. Then i made a make modules, make, and make install. Everything is fine so far. After that, i edited kamailio.cfg the loadmodule for snmstats.so and when i launch kamailio I have the following error : "kamailio: ERROR: <core> [modparam.c:166]: set_mod_param_regex(): No module matching <snmpstats> found" I also made a ldd : # ldd -v -d -r /usr/local/lib64/kamailio/modules/snmpstats.so linux-vdso.so.1 => (0x00007ffff53ff000) libnetsnmpmibs.so.30 => not found

? By the way I configured /etc/snmpd.conf by adding the line "master agentx" and created a file /etc/snmpstats.cfg with only one line : "agentXSocket tcp:localhost:705". Is that correct ? Do i need to reload something after modifing those files ?
