L.E. : apt-get doesn't find the library even after an update/upgrade. My

[SR-Users] NSQ libevbuffsock dependency

[smititelu]

Hi,

Upon trying to compile latest Kamailio from sources I got an:
"
nsq.h:9:24: fatal error: evbuffsock.h: No such file or directory
 #include 
^
"

Looking on the new NSQ module documentation I see the libevbuffsock 
dependency. Is there other  recommended way, to install the library 
besides compiling from sources at [1]?


Thx,
Stefan

Hi,

There have been quite a lot of changes in rtpengine module mainly relate 
to the possibility to store/get rtpengine machine URL in/from database.


Among those changes, [1] has been introduced also. This is useful when 
you have many sets of rtpengine stored in database and want to select 
the active set, currently possible only at startup-time (devault those 
with setid 0). A further improvement here would be to be able to "kamctl 
fifo change it".


The message notices that you should set [1] to your wanted, active set.




Subsequently to that, Kamailio starts normally and connects to rtpengine:

May 03 17:18:22 allegro-4.evaristesys.com 
/usr/local/sbin/kamailio[24972]: INFO: rtpengine [rtpengine.c:2542]:

/usr/local/sbin/kamailio[24974]: INFO: rtpengine [rtpengine.c:2542]: 
rtpp_test(): rtp proxy  found, support for it enabled

[...]

It might be something on my end, but my guess is that in v4.4 there is 
a fixup that runs beforehand and looks for a default set.


Strictly speaking, I don't need an explicitly identified set, since 
I'm only using one rtpengine instance. However, I explicitly specify 
it because I'd like the code to be open in the future to selecting a 
given rtpengine relay based on some criteria.


-- Alex

Now, having "modparam("rtpengine", "setid_avp", "$avp(setid)")" 
overwrites [1]'s behaviour, explaining why it's "found, support for it 
enabled".

Stefan

Re: [SR-Users] rtpproxy does not response, disable it

[smititelu]

I solved this problem by changing the 127.0.0.1 in rtpengine startup 
config into 10.109.247.90 which is the eth0 address of the rtpengine 
machine.


Now Kamailio successfully connect to the rtpengine daemon.


Nice you solved it. Didn't think of it :D

Re: [SR-Users] rtpproxy does not response, disable it

[smititelu]

I’ve already set modparam("rtpengine", "force_send_interface", 
“10.109.247.80”) in my kamailio.cfg from the very beginning.
Can you try force ping from kamailio machine (.80) to rtpengine machine 
(.90), on 10.109.247.80 interface? (it should work)



There is nothing prompt out on command “kamctl fifo nh_show_rtpp all”
If there is nothing shown it means that kamailio sees no rtpengine 
nodes. What kamailio/rtpengine version are you using? (are they both 
latest upstream?!). The sock line should be fine: modparam("rtpengine", 
"rtpengine_sock", "udp:10.109.247.90:7723")


Can you increase the log level(debug=3) and send some debug info on 
what's happening right after you restart kamailio?(for rtpengine module)


There is nothing captured on "ngerp -W byline -d em1 port 5095” on 
Kamilio machine.
Wehn eventually you see something for the show ctl command, you should 
try capturing for dst port 7723, on kamailio machine, to see the 
commands sent to rtpengine.

Re: [SR-Users] rtpproxy does not response, disable it

And, I also tried to set Kamailio and rtpengine daemon in a same 
machine,and use modparam(“rtpengine”, “rtpengine_sock”, 
“udp:localhost:7723”). And Kamailio can work functionally under this 
situation. rtpengine daemon can receive ping message from Kamailio and 
rtpengine daemon can work as suspected. So for the later case, is it 
supposed that Kamailio be in the same machine with same localhost 
address? Otherwise, what’s the reason for my ERROR?

You can try make use of the below parameter:

# Which local interface/IP should be used for the control channel
modparam("rtpengine", "force_send_interface", "X.X.X.X")

Hi Zodiac,

1. Can you see your configured rtp node on: "kamctl fifo nh_show_rtpp all" ?
2. Can you ngrep the commands being sent by kamailio to rtpengine?(on 
both kamailio and rtpengine machine)

3. Do you have some firewalling rules that may block that 7723 port?

[SR-Users] why msg_apply_changes() from REQUEST_ROUTE only

[smititelu]

Hello,

I don't understand why msg_apply changes() can be called from 
REQUEST_ROUTE *only*. Can someone explain? Can this be extended to 
*FAILURE_ROUTES *also?


Basically I need to call this from FAILURE_ROUTES in order to avoid 
double SDP for rtpengine offers. Searching in the mailing list I could 
see that there could be other means of handling this like keeping and 
reading the SDP from an avp(write/read_sdp_pv), but I find the above 
method pretty straightforward.


Thanks,
Stefan

It is related to the pull-request for rtpengine hash table to keep the

using rtpengine's via-branch feature. We are running it for ~ two weeks 
from now, in the test system, and didn't spotted problems so far 
(without via-branch).

I think of both.

I can easily add the generated database script files(e.g. utils/kamctl/

with the description of db tables.

Re: [SR-Users] How to dump or log the value of $avp(ice_priority) with xlog

[smititelu]

Hello,

Try using|||dbg_pv_dump |from the kamailio debugger module. The output 
should also include your avp.


Alternatively, you could use interactive debugging with kamcmd: kamcmd 
dbg.bp eval 3016 $avp(myvar) as described in the above module. To do 
this you need to kamcmd dbg.bp on to set breakpoints in the kamailio 
procs, followed by dbg.ls, dbg.next, dbg.eval as the Usage example 
shows. You _must_ enter the kamcmd shell for dbg.eval to work; for me, 
it didn't worked otherwise(i.e. when trying non-interactively).


Alternatively, you could set the breakpoint(1) module param to enable 
line by line breakpoints or use dbg_breakpoint(1) function in .cfg 
file, though the latter didn't work for me and I belive is not yet 
implemented. (as w_dbg_breakpoint function says).

Stefan
