Kamailio behind DSL router
by Muhammad Shahzad 03 Feb '14

03 Feb '14

Hi, I am setting up Raspberry Pi to run Kamailio with mediaproxy-ng. This machine is running on local LAN behind a DSL router. Using dynamic DNS and DMZ services of router, i can access this box from the Internet. However, i do not know how to define advertised_address parameter to public IP of router. The public IP is dynamic and changes roughly every 12 hours or so. Is there any way kamailio can automatically learn this dynamic public IP and use that as advertised_address? Something similar to Asterisk's res_stun_monitor module, https://reviewboard.asterisk.org/r/854/ Any help will be greatly appreciated. Thank you.

Packet loss / Jitter / Latency issues
by Wingsravi R 02 Feb '14

02 Feb '14

Dear Daniel and Kamailio'ns Greetings, I am working on kamailio server (4.0.x),whicch is integreted with media-proxy server (2.5.2) and it is all working fine in the point of SIP functionality. And i have a set-up like this below, with this when the calls (audio/video) sessions started i am experiencing latency,jitter, echo's in audio calls and a choppy ,pixelled video : KAMAILIO | Android SIP client (IMSDroid) ---- Wi-Fi router ---- Switch (level 2) ---- Wi-Fi router ---- Android SIP client (IMSDroid) (Total set-up runs on Intranet infrastructure). When i call between two SIP clients, Calls are getting established successfully and RTP flow is also relaying using Media-proxy server. But the audio/video performnce is not good enough. I am experiencing all this Latency , jitter , Choppy pixelled video. How can i resolve all this issues? What could be the problem ? Ofcourse SIP proxy is not responsible all this problems (as i know ), But is there anything can be done on Media-proxy server ? Or anything Buffer settings can be done on Kamailio server side (or anything else) ? Even i changed Shared memory and Package memories to 512MB and 16MB respectively. Anybody can guess what may be the problems that causes these issues ? PS: When i tried 'ping' Clients IP addresses in Kamailio server PC, there is 20-30% packet loss also. Please help me in resolving these issues. Any help will greatly appreciate. Regards, Ravi.

John, What db_mode are you using for dialog module? Are the entries in the db if you check manually? Are you able to fetch other data using avp_db_query? And do you see any errors in the log?

Hello, I am managing calls with the dialog module in kamailio 4.0.4. However if is try to get the callid and from_tag of existing calls using: avp_db_query("select callid, from_tag from dialog", "$avp(s:s_callid), $avp(s:s_from_tag)"); I get NULL, yet if I use: sercmd proxy dlg.list I get the calls listed correctly. What am I doing wrong? Thanks John

Kamailio without tls
by Neville D'Souza 01 Feb '14

01 Feb '14

Hi Support, I have recently kamailio 4.0.x version with tls on port 5061. Now our development team needs to connect to it using unencrypted on port 5060 to test an app for features and then work towards connecting through tls connection. So my question is how do I temporarily disable tls to test all the features on the kamailio server and then once feature testing is done revert back to tls connection? Best Regards, Neville D'Souza

kamailio 4.1.1 failure routes issue
by José Seabra 01 Feb '14

01 Feb '14

Hello there, I think that i found a bug within failure routes on version 4.1.1, i have a call flow that needs to use the failure routes 4 times if nobody answer the call, but when the call goes to the 3º attempt to same failure route kamailio doesn't handle the transaction, With the same kamailio script but using the version 4.0.1 kamailio works correctly. Please check the attachment with kamailio debug level 3 -- Cumprimentos José Seabra
