Hi,
I have started using kamailio recently. Added to db almost 100K users. And
now I am trying to increase shared and private memory with this command
when server is running: kamailio -M 12 -m 128. But then I check it with
`kamailio -l` and the same values (64 and 8 respectively) are there. Can I
change it with config? or what I do wrong.
And what's the purpose of child process? - Will kamailio process requests
faster if I set child=32 (for example)?
Thanks and best regards,
Volodymyr
So I'm building a load balancer solution that needs to monitor remote devices at a specific interval via snmp for certain data (channels and cps) and use that data to create a dynamically updated weight for each of the destinations. I can't find any reasonable mechanism for updating the weight attribute in the dispatcher module itself without having to do some hacky "update the database column then trigger dispatcher.reload" script, which I very much want to avoid.
Is this something I should just be thinking of ditching the dispatcher module and rolling my own design or am I missing something obvious?

Hi All,
I'm having a wee little bit of difficulty in trying to load-balance
registrations to multiple servers based on their weights.
Kind of similar scenario as discussed in this thread:
http://lists.sip-router.org/pipermail/sr-users/2014-December/086235.html
The problem I'm facing is that dispatcher is always choosing the first
destination from the group.
I do suspect that dispatcher is not considering registrations as load at
all and only counts INVITES as load.
If above is correct then is there a way to use dispatcher to count
registrations as load ?
Thanks,
Sammy
Hi,
I wanted to raise the possibility of an inline signalling-only B2BUA
component to Kamailio.
I know that's an extremely poor fit for Kamailio, and not at all what
it's supposed to do. And there are many things about the OpenSIPS B2BUA
module that reveal how awkwardly it is situated, as a square peg in a
round hole. I myself am philosophically opposed to a B2BUA in Kamailio
to the threshold of physical violence.
However, the reason I bring it up for discussion is that there are very
few viable, high-performance signalling-only B2BUA alternatives that are
FOSS. There is enormous demand for a B2BUA, mainly for topology
concealment purposes, from the short-duration traffic industry, which
many users of Kamailio deal with. It's why a lot of them end up going to
OpenSIPS; they need the B2BUA, and prefer to consolidate on one OpenSER
brand.
Anyone who has tried to run high-CPS traffic through the existing FOSS
signalling-only B2BUAs out there situated in front of Kamailio has
discovered, sometimes in a very financially painful way, that:
- FreeSWITCH falls over at around +/- 300 CPS.
This is with RTP relay disabled -- signalling-only. It requires
horizontally scaling a large number of FreeSWITCH boxes to meet a
capacity requirement of, say, 2000 CPS, which is unfortunate given the
favourable proposition offered by Kamailio for the infrastructure unit
economics. In other words, it's ironic to have to build a fleet of 10
FreeSWITCH boxes for the 1% problem of topology concealment when
Kamailio can otherwise churn through 2000 CPS with no issues.
- SEMS' 'sbc' module is a good candidate and can handle the load, but
Frafos offers practically no support for it, with all efforts focused on
their commercial ABC SBC product. That's very understandable, but just
not practical given the high technical knowledge SEMS requires to deploy
and maintain in this capacity.
- None of the other userspace B2BUA folk traditions can handle the load.
So, like I said, I personally recoil in shock and horror at the idea of
introducing a B2BUA into something that was designed to be anything but
a B2BUA. But, there is a huge market opportunity for this functionality
in North America, and at the moment, users who need it are mostly ending
up in OpenSIPS land.

Hi!
Is there any possibility to set Expires in PUBLISH message to never in
Presence module?
I want to have BLF’s that indicates states, that driven via PUBLISH, but
can be really irregular (let’s say once a week)

Hi everyone i am installing Kamailio to scale asterisk on a remote hosted server in a way to manage calls dialogs in a real-time fashion. (and to manage many customers)
Several users (maybe 80) are working at the head-office and i want them register their hardphone on the remote Kamailio Ipbx, to free them of ours end-of-life PABX (alcatel-Lucent).
Can kamailio help me to achieve that ?
What kind of software have I to install locally (mysql to replicate the master mysql db? a replicated asterisk instance?) ? Taking into consideration disaster recovery plan What could be my options to maintain internal call if my internet provider get down by exemple.
thx you for your idea.

Hello,
I have a need to deploy Kamailio in AWS in a scenario of this sort:
[Public Internet] <---> Kamailio <---> (Internal AWS servers)
In such a scenario, Kamailio would be multihomed.
Furthermore, in addition to sending out of two distinct network
interfaces, the networking idiosyncrasies of AWS needs to be taken into
account. AWS hosts only have an RFC1918 address homed natively,
front-ended by 1:1 NAT externally. Normally, this is taken care of by
advertised_address, which allows Kamailio to make outward
representations about the network address by which it can be reached
that are different to the IP to which it is bound.
The problem here is that I need to do this conditionally, only on
traffic going out the public interface. It should not be done on
messages going to the "internal AWS servers".
So, the questions that arise are:
1. Is this sane? Any unforeseen effects, e.g. vis-a-vis RR, provided
enable_double_rr is enabled and that two genuinely different network
interfaces are used?
2. Do set_advertised_address()/set_advertised_port() accept PV
arguments, or are they pre-PV "core function folk traditions" in the
same way as rewritehostport() and force_send_socket()?
Thanks!
