Hi,
I'm using the UAC module in Kamailio to setup about 500 outbound
registration towards a single host.
The issue I'm currently experiencing is that when we start Kamailio all
this 500 registrations are initiated at once towards the host which can't
handle all the requests at the same time.
Therefor I tried to spread the registrations using the reg_random_delay
function:
modparam("uac", "reg_random_delay", 60)
I would expect that this would spread the registrations over about a minute
but in reality the registrations are spread as follow:
Starttime / Registrations
21:59:14 151
21:59:15 166
21:59:16 127
21:59:18 60
21:59:22 35
So Kamailio is started at 21:59:14 and initiates 151 registrations,
1 second after start another 166
2 seconds after start another 127
4 seconds after start another 60
8 seconds after start the last 35
In reality it looks like some increment is applied instead of calculating a
random starting offset for each outbound registration?
Is there any solutions to this issue available?
Best regards,
Ivo Vastert
Hello All,
I read rtpengine can multiplex and demultiplex RTP/RTCP.
Cf.https://github.com/sipwise/rtpengine
Example:
UAC -> Kamailio + rtpengine -> Asterisk
UAC and Asterisk don't support RFC 5761. Only rtpengine does.
Does this mean that uac must be compliance with RFC 5761 if I want
multiplex and demultiplex RTP/RTCP between UAC and rtpengine?
Thanks.
Abdoul.

Hello.
Doing a new install, and I am in the stage of accessing the web interface
for Sermis which is located at /var/www/html/siremis
Full error: Unable to write in the session save path
[/var/www/html/siremis/session]Unable to write in the session save path
[/var/www/html/siremis/session]
I would think this is a single access problem, but I have checked ownership
in httpd.conf, and the files, and directories. All have the apache ownership
assigned to them. I have even given the "session" folder access of 777 with
still no change in the error.

In addition, there is nothing about this appearing in the httpd error_log,
nor access_log for an access problem.
Any suggestions? Thanks!

Hi
We are experiencing issue with python script KSR.pv.get using branch 5.0.2 as it fails "unable to get pv value"
Example Code:
if KSR.pv.get("$ai"):
fromid = KSR.pv.get("$(hdr(P-Asserted-Identity){uri.user})")
Error:
Aug 14 18:38:23 sbc99-kam-dev /usr/sbin/kamailio[30459]: PYT {INVITE}: ERROR: app_python [apy_kemi.c:637]: sr_apy_kemi_f_pv_get(): unable to get pv value for [$(hdr(P-Asserted-Identity){uri.user})]
Is anybody have any idea how to workaround?
Many Thanks

Hello,
We're testing kamailio 4.3.4 with two kamailio's communicating with each other. One of them is a gateway with rtpengine at the carrier side, the other is a basic sip router.
When calling a destination and cancelling the INVITE a 487 is received from the carrier and directly ACK'd by the first kamailio and in turn is forwarded to the second.
But the 487 response received by the 2nd kamailio doesn't have a Via header which results in kamailio printing the error: receive_msg(): no via found in reply.
Any ideas why the forwarded 487 doesn't contain a Via header and how to fix this?
Note: IP's are changed.

Finally I find a root of a problem with my T.38 reinvites.
A->(NAT)->Kami->PSTN
When NATted caller does reinvite, and remote side answers with 200
OK+SDP, Kami (why?) doesn't rewrite SDP for its own IP (so NATted
caller can receive RTP) and leaves remote's IP as media address, so of
course there is no RTP/UDPTL. All other NAT related stuff works fine.
Even if remote side sends me T.38 reinvite first, everything works
properly. Config file is default from Kami sources.
Any ideas?
