gateway connection
by Joli Martinez 18 May '14

18 May '14

Hello, I have setup Kamailio with Freeswitch and it is working. Right now I have my SIP providers connected to Freeswitch. Would it make sense to connect my SIP providers to kamailio instead. My setup will be intended to resell minutes. If so what advantages will I gain by connecting my SIP providers to kamailio

fetch bindings- timeout
by Daniel Ciprus 16 May '14

16 May '14

All, According to RFC3261: 10.2.3<http://tools.ietf.org/html/rfc3261#section-10.2.3> Fetching Bindings A success response to any REGISTER request contains the complete list of existing bindings, regardless of whether the request contained a Contact header field. If no Contact header field is present in a REGISTER request, the list of bindings is left unchanged. We should be able to fetch bindings from registrar. With my very limited knowledge of kamailio code (dialog-ng/… [View More]

Just 80 call/second
by Andrea Meroni 16 May '14

16 May '14

Hi all, i have some strange performance issues (with Kamailio config file i guess): using the default configuration file i can reach a 500 call/s rate, while using the default configuration file in the dispatcher folder i can reach just a 80 call/s rate (using the dispatching failover algorithm ...). The dispatcher is in front on a very basic Kamailio-based IMS core. Something has some hint about this issues? Andrea

Dispatcher poor performance
by Andrea Meroni 16 May '14

16 May '14

Hi all, i have a strange performance problem: i placed a dispatcher in front of a bundle of Kamailio proxies and, even with a really simple dispatching logic route { #ds_select_dstl("1", "2"); $du="sip:192.168.100.51:5060"; forward(); } that actually doesn't even use the dispatcher module i get that when the server's (192.168.100.51) CPU is 100% used the dispatcher's CPU is ~50% used. Using the dispatching algorithm based on the hash of the From-URI or the failover … [View More]

HI Alex, Thanks for the suggestion. I tried using the function sl_send_reply(msg, 403, "Forbidden") in the receive.c file after including the header files. But the following error is coming when compiling the kamailio.

Hi All, I am using the sl_send_reply function in the receive.c file. In included the header file sl_funcs.h correctly in the receive.c and receive. compiles fine.

Duplicate values in SDP
by VOIP Tests 16 May '14

16 May '14

Hello, Can some one let me know the reason that there are these duplicate values in the SDP ( o, c, m, nortpproxy)? Our server was working with kamailio and asterisk on the same machine and had no problem. When we separated kamailio and asterisk on different servers and added the dispatcher module I see this error because of which there is not audio from an incoming PSTN call. 2014/05/15 18:55:19.972332 172.10.30.8:5060 -> 66.136.17.30:5060 SIP/2.0 200 OK.

by Sebastian Damm 15 May '14

Hi, I'm trying to fill a hash table on startup in the htable:mod-init event route. But it doesn't work. Kamailio doesn't start at all, but doesn't print out an error in the log. This is what the route looks like: event_route[htable:mod-init] { xlog("L_NOTICE", "Loading Carrier domains into Hash table.\n"); sql_query("ser", "select domain_name from carrier_domains", "domains"); xlog("L_NOTICE", "Loaded from database...\n"); while($var(i)<$dbr(domains=>… [View More]
