Indeed, this is one advantage of using an in-memory cache.

The cr module support also a extended matching mode, but it will be probably not really feasible with millions of routes: http://kamailio.org/docs/modules/stable/modules/carrierroute.html#id2651893 Another thing you could do is use another "domain" for the D prefix, e.g. one for the default routing, and then another one for the D case. The module support matching for the domain as well. You could maybe also use flags for matching. Other possible modules for PSTN routing are lcr and mtree. Regards, Henning

Using SR for Number Translation & Number Portabilty Applications

by Yaron Nachum

Hi Everyone, I have downloaded SR r 3.1.4 and have been playing around with it. I am considering implementing Number Translation services (1800...) and Number Portability Services on it. We have around 20K entries on the Number Translation Service and around 3M entries on the Number portability Service. The volume is around 100 caps. I have started working with the carrierroute module - it seems perfect for the Number translation Service, but I am not sure about the Number portability. I have several questions: 1. Is it possible to use this module with several millions of entries? 2. What is the impact of loading the table? Is it possible to do it during traffic hours? I have read about PDB module, but I haven't understood how to setup the PDB server. I would appreciate for any guidance. Would you recommend using the PDB module for the Number Portability or the carrierroute? Thanks.

Dear sirs, searching on the web and in old ML threads about the suggested number of TCP and UDP workers, I just found: - for TCP children (i.e., TCP receivers, isn't it?) "As a rule of thumb, (maximum simultaneous connections)/2000 should be OK" (from doc/tcp_tunning.txt) - In general for workers (from a past thread by Henning Westerholt): "In my experience the number of children is not that important for performance, you may just choose the default size of 8." In the last post there was, moreover, a suggestion that the number of children should be chosen with respect to RAM and CPU cores (that makes sense to me). The only thing I can think about the rule of thumb above comes from the possibility that a number of processes may be unavailable in blocking operations. So my question is: - with asynchronous TCP/TLS is it safe to assume that more children than CPU cores are more or less useless? - are there other blocking operations for which the number of UDP/TCP children should be incremented above the CPU cores number? Thank you! Best regards, Francesco Castellano

Homer Project

by Alexandr Dubovikov

Hello sr-users, I would like to present a new project called "Homer". What is Homer ? Homer is a capture solution for SIP logging. How does it work? Homer has 4 components: 1. Capture Agent 2. Capture Node 4. Capture DB 3. Web GUI. The capture agent takes your local SIP traffic and sends it to the defined capture node in HEP protocol. If you are user of FreeSWITCH or Kamailio, use build-in capture agent. In other case, you can use an external generic daemon, but only for SIP/UDP. The capture node is based on kamailio, can receive SIP traffic encapsulated in IP proto 4 (IPIP) or in HEP procotol and store it into MySQL DB. To gain access to the capture DB, download a simple webinterface (PHP based). After it you are able to do search, generate PCAP file, callflow, look at the details of SIP messages etc. Homer works in our company and easy collect ~5 M packets per hour. The patches for kamailio and some other information can be found here: http://homer.googlecode.com Beta testers are welcome :-) I'll help everybody to setup/configure Homer :-) With best regards, Alexandr

$du gets set automatically before branch_route

by Alex Hermann

Hello, while trying to upgrade from 1.5 to 3.1 i noticed that between t_relay() and branch_route, $du gets automatically set to $ru if it has not been set before. This is a change from 1.5 i could not find documentation for, so it might have been unintened. Can someone enlighten me on the purpose of this change and if there is a way to determine if $du is (was) unset other than comparing $ru to $du, wich seems a bit inefficient? Is it even guaranteed that $du gets set to $ru in every possible scenario? -- Alex Hermann

Kamailio on a server with different network cards

by Rocío Ruz

Hello, My server has two different network cards with different IPs. I want kamailio to use both; the network card to be used depends on the destination. My problem is that I have to add an IP in the configuration file kamailio.cfg: listen=109.239.50.67 Will Kamailio listen only to packets sent to this IP? Can I add the two IPs corresponding to my two network cards here? Thank you RR

How to reset t_on_failure/branch?

by Iñaki Baz Castillo

Hi, I remember that in Kamailio 1.5.X t_on_branch and t_on_failure still remain after rouning failure_route[XX], and I "think" there was a way to reset them. In 3.X it seems that t_on_branch and t_on_failure must be set again in failure_route to take effect in next t_relay() call, am I right? Thanks. -- Iñaki Baz Castillo <ibc(a)aliax.net>
