Audio quality issue
by Austin Einter 10 Oct '11

10 Oct '11

Hi I am using Kamailio 3.1.5 . I am using RTP proxy also. I have used default kamailio.cfg.sample fiile , and just added line #!define WITH_NAT. I have another Main proxy. I wanted all my signalling and media packets should just pass through machine where Kamailio and RTP proxy are running. With this I found, call is established, all signalling and media packets are passing through kamailio / rtp-proxy. So far so good. One way audio stream (from called party to calling party) quality is good. The other audio stream (from calling party to called party is very bad. Did anybody face this issue? Please help me to sort out this issue audio quality issue. Regards Austin

by Mino Haluz 10 Oct '11

10 Oct '11

Hi, is there any setting which could allow me to set maximum memory per module ? As I am testing the carrier route module, I've added for testing purposes 100 000 rules sofar. When I start the kamailio, it gives me : Oct 10 14:46:46 kamrouter /usr/sbin/kamailio[2182]: ERROR: carrierroute [../../ut.h:702]: could not allocate shared memory from available pool Oct 10 14:46:46 kamrouter /usr/sbin/kamailio[2182]: ERROR: carrierroute [cr_rule.c:155]: could not allocate shared memory from available pool Thanks.

by Austin Einter 08 Oct '11

Hi Just a quick question. How memory is allocated in Kamailio code. Few places I saw pkg_malloc function. Is it the only function used to allocate memory or there are similar functions present in kamailio. Thanks Austin

Kamailio RTP Proxy Questions
by Austin Einter 07 Oct '11

07 Oct '11

Hi I downloaded 3.1.5 Kamalio source, did make and install. Tried to run, and tested few basic scenarios, everything working fine. I have a main proxy, want to use kamailio as intermediate proxy and my requirement is all RTP packets should pass through machine in which Kamalio proxy is running. I beleive RTP Proxy I can run in same machine where Kamailio proxy is running with proper configuration . For this I am referring, http://nil.uniza.sk/sip/nat-fw/configuring-nat-traversal-using-kamailio-31-… page. In one of the steps it says "So, if we are using the Rtpproxy server with default configuration, we have to open /etc/default/rtpproxy file and uncomment following line regarding of udp socket, that will be sued for interconnection:". I tried to search rtpproxy configuration file, could not locate. While making and installing Kamalio proxy, the commands I used "make prefix=/usr/local/ all and make prefix=/usr/local/ install". Can somebody point me why rtpproxy config file is missing. Also the link I am refering to is correct or wrong one. Best Regards, Austin

Multiple INVITEs and discarded call_control
by Mino Haluz 07 Oct '11

07 Oct '11

Hi, my kamailio server is receiving from some customers 3 identical INVITEs when call is initiated (separated by 200ms). Those 3 INVITEs are making a big problem with call_control: WARNING: call_control [call_control.c:1156]: dialog to trace controlled call was not created. discarding callcontrol. That is why, the prepaid limit is not working at all in this case. This way the user can hack the prepaid protection of the account. Otherwise the call_control is fuilly functional. Anybody experienced the similar problem? If so, how to resolve it? Thanks, Mino Haluz

Hi! Kamailio 1.3.4: "kamctl ul monitor" causes: ERROR: <core> [attr.c:80]: no more pkg mem (21) ERROR: mi_fifo [fifo_fnc.c:513]: command (ul_dump) processing failed There are ~ 2000 entries in location table. Default PKG size is used. I remember there were some similar reports recently, but couldn't find the relevant threads. Any hints for the cause of this problem and workarounds? Thanks Klaus

Problems with domain on registrations.
by Henrik Aagaard Sørensen 06 Oct '11

06 Oct '11

I have the current setup: SIP client <-> SER Proxy <-> SIP Trunk. My reason for the SER Proxy is that the SIP trunk only allows connections from approved IP addresses (such as my server with SER Proxy). My user on the SIP Trunk has the following authentication username@domain. I am able to register to the SIP Trunk as I'm setting up my SIP klient with username to username, domain to domain and then add my SER Proxy IP address as proxy. This works and means that I'm able to place calls to the SIP Trunk. BUT people cannot place calls from the SIP Trunk to my SIP client, due to the fact that on the SIP Trunk my locations is registered as username@SER-Procy-IP. So when people are calling me, the SER Proxy is looking for username@SER-Procy-IP and NOT username@domain, as I'm registered with. And then SER Proxy reports: 404 Not Found. Can anyone help me how to set this up correctly? I do not have access to the SIP Trunk, but I have all access to the SIP client and SIP Proxy.

Removing Contact from location table when TCP connection from UA is dropped...
by Krishna Kurapati 06 Oct '11

06 Oct '11

Hi, When UA connects with the Proxy over TCP, the contact is mostly bound to the firewall's binding IP and port for that connection. When the connection is dropped, the contact in Kamailio is no longer valid even though there is time left to expire the contact. Is there some way to link TCP connection and the contact in such a way that when TCP connection is dropped, contact from the location can be removed? Thanks Krish Kura
