Multiple calls uac_replace_from()
by Alex Balashov 19 Mar '13

19 Mar '13

Forgive me if I failed to follow a recent discussion to its conclusion, but what is the bottom line on calling uac_replace_from() consecutively, in the course of processing one request? Is it possible, while using restore_mode 'auto'? Is there a correct way to do it, such as calling msg_apply_changes() after the first call but not the second one? If not, what is the alternative? -- Alex -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/

Survey on SIP overload control
by Yang Hong 18 Mar '13

18 Mar '13

Dear all, SIP overload may block too many calls unnecessarily. "Requirements for Management of Overload in the Session Initiation Protocol. IETF RFC 5390." http://www.ietf.org/rfc/rfc5390.txt Build-in overload mechanism cannot prevent overload effectively. Therefore, IETF SIP Overload Control (soc) Working Group works on IETF RFC "SIP Overload Control" currently. http://tools.ietf.org/html/draft-ietf-soc-overload-control-12 IETF SIP Overload Control discussion archives http://www.ietf.org/mail-archive/web/sip-overload/current/threads.html#00874 We have published a survey on SIP overload control algorithms (including IETF RFC "SIP Overload Control"). http://www.researchgate.net/publication/231609451_A_Comparative_Study_of_SI… http://arxiv.org/abs/1210.1505 http://www.igi-global.com/chapter/comparative-study-sip-overload-control/67… We have also used control theorectic approaches to model the interactions between an overloaded SIP server and its upstream servers as a feedback control system in two different scenarios - redundant retransmission ratio control and round trip delay control (IEEE Globecom 2010 and ICC 2011). "Mitigating SIP Overload Using a Control-Theoretic Approach" IEEE Globecom 2010 http://www.researchgate.net/publication/221284946_Mitigating_SIP_Overload_U… http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=5683124&url=http%3A%2… Implementation of implicit SIP overload control in the real system "An Efficient Earthquake Early Warning Message Delivery Algorithm Using an in Time Control-Theoretic Approach" http://link.springer.com/chapter/10.1007%2F978-3-642-23641-9_15# "Design Of A PI Rate Controller for Mitigating SIP Overload" IEEE ICC 2011 http://www.researchgate.net/publication/224249824_Design_of_a_PI_Rate_Contr… http://features.rr.com/article/01vBgtc8TR17z?q=Skype http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=5963029&url=http%3A%2… Best regards, Winston Hong Software Engineer InBay Technologies Inc.

Kamailio strange behavior : bad Via, bad port
by Khoa Pham 18 Mar '13

18 Mar '13

Hi, When A calls B. The INVITE goes through Kamailio. In the Kamalio 's log file, I see it say "bad Via", bad port. And it doesnot reply A with 100 Trying not forwarding INVITE to B. The INVITE message (espcially the Via header) is OK. This problem sometimes happens. Do you know why ? Please help. Thanks -- Khoa Pham HCMC University of Science Faculty of Information Technology

Kamailio not send 100/180 for INVITE !
by Khoa Pham 18 Mar '13

18 Mar '13

Hi, When A calls B. Kamailio will handle A's INVITE message. But I see that B doesnot receive the INVITE. And A doesnot receive any 100/180 privisional message. Why does Kamailio not send 100/180 ? Please help -- Khoa Pham HCMC University of Science Faculty of Information Technology

How does Kamailio handle INVITE message by default ?
by Khoa Pham 17 Mar '13

17 Mar '13

Hi, After asking many questions, I haven't got any clues about how Kamailio handles INVITE message by default, in terms of modifying c= line in SDP According to rtpproxy flow http://kamailio.org/docs/ser-getting-started/SER-GettingStarted.pdf When client register, SIP proxy will call nat_uac_test() to detected if client is NATed or not, then save this info. When client A calls client B, the INVITE message will go through SIP proxy. Here the SIP proxy can do 3 things (as in section "INVITEs behind NAT" in the pdf). 1. Add an SDP command direction:active to the SDP content 2. Change the c= line to a.b.c.d 3. Force RTP to go through a proxy by changing the c-line to c=IN IP4 address-of-proxy and the m-line to m=audio port-on-proxy RTP/AVP 0 101. When will SER do 2, 3 ? -- Khoa Pham HCMC University of Science Faculty of Information Technology

Kamailio only allowing traffic with machines in the dispatcher.cfg?
by Benjamin Henrion 16 Mar '13

16 Mar '13

Hi, Does someone know/uses a simple rule so that Kamailio only exchanges traffic with machines in the dispatcher? Best, -- Benjamin Henrion <bhenrion at ffii.org> FFII Brussels - +32-484-566109 - +32-2-3500762 "In July 2005, after several failed attempts to legalise software patents in Europe, the patent establishment changed its strategy. Instead of explicitly seeking to sanction the patentability of software, they are now seeking to create a central European patent court, which would establish and enforce patentability rules in their favor, without any possibility of correction by competing courts or democratically elected legislators."
