I'm just starting to evaluate Kamailio to be used as a front end to a couple of Asterisk Servers. Currently I have an Adobe Flex application that interfaces with Asterisk via AMI using a socket connection. I searched on how to interface with Kamailio but wasn't able to find anything that helped me. I would appreciate it if someone could point me to where I can find information on how this can be done using Kamailio. For example I would like my Flex Application to connect to Kamailio to know the status of the SIP channels. Thanks for any help!!! Carlos

new feature: option to remove contacts based on sip nat keepalives

by Juha Heinanen

daniel, you wrote: This feature should be useful in mobile networks, to avoid stacking lot of invalid contacts which could result in lot of branches causing many retransmissions. why would a sip ua that runs in a mobile network device be configured to use udp instead of tcp? poor battery life seems to be a big problem in so called smart phones. wouldn't this kind of active pinging make it even worse? -- juha

Websocket INVITE 407 error

by David Patiño

Hi there, I'm new on kamailio users list. Now I'm developing a client in javascript (using websockets) to SIP calls. I'm using last devel version of kamailio with websocket support. I've already get a correct REGISTER transaction but now I'm not able to get a correct INVITE transaction. Actually I'm not sure if this a kamailio error or a problem with my source code however I'm using the same function to get digest info from received nonce both REGISTER and INVITE transactions. The INVITE transaction always enters in an endless loop with 407 requests. Please, is there anybody who could help me? Those are the frames of my code (obtained from chrome browser console): wsUri: ws://10.1.20.40:80/ SOCKET CREATED SOCKET OPENED SENT: REGISTER sip:10.1.20.40 SIP/2.0 Via: SIP/2.0/WS

SIP routing configuration howto

by Kaplan, Michael A

Folks, I'm working on a 5 node network in the following topology: Host1 - Edge Proxy 1 --- Core Proxy - Edge Proxy 2 - Host2 The proxy machines contain SIP Server installations, the hosts contain user agent software. I am able to make a call end to end between the hosts, but when I look at the traffic in wireshark, the core proxy is actually just forwarding the messages at the IP-layer. I would like actual SIP routing to occur, where a host would send the INVITE to the edge, and the edge has to forward it to the core etc, with these messages actually being processed at the SIP layer for all proxy nodes. I've been trying to use the dynamic routing module, thought I'm not sure this is really right for what I need, simple static routing would likely work as well. Is it necessary for me to rewrite the route{} functions of a proxy script? I'm not sure if I'm approaching this problem the right way. Eventually I would like to have multiple core servers and be able to failover between them, but trying to keep it simple for now. Thanks, Mike -------------------------------- Michael A.

Send/Receive IMs

by Marty Beyers

Hey guys. I am very new to Kamailio. Basically, at this time, I want to generate a SIP message (from an SMS) within Kannel, and send this message to my Kamailio server, which will forward the SIP message to another SIP server. Therefore my Kamailio Sip server would act as a single user agent connecting to only one other SIP server. So what I am unsure of is: 1. Is there a Kamailio interface (such as an HTTP server) which Kannel can connect to in order for Kannel to send multiple messages to my Kamailio Server, which in turn would be forwarded as SIP instant messages to another SIP server? 2. Which Kamailio api can I use to formulate and send the SIP instant messages? 3. Which Kamailio callback function could be called when I receive acknowledgement responses to the SIP IMs I have sent? 4. Which Kamailio callback function could be called when I receive new SIP instant messages sent to me? It would be great if someone could help point me in the right direction. Many thanks. Fred

SUBSCRIBE/NOTIFY record route

by Spencer Thomason

Hello all, I'm using Kamailio (on a public IP) as a border proxy that handles NAT traversal (detection and keep alives) for several Freeswitch servers which have public IPs as well. I'm having a problem record-routing SUBSCRIBEs and NOTIFYs for nated UACs. If the UAC is behind NAT, I am adding a Record-Route to the initial SUBSCRIBE and NOTIFY request. This works great until the UAC (in this case a Cisco SPA509G) refreshes the subcription and sends the SUBSCRIBE directly to the Freeswitch server. Since the request doesn't pass through the proxy, Freeswitch then sends NOTIFYs directly to the UAC which only recieves the first NOTIFY as the NAT pinhole is still open from the SUBSCRIBE. The UAC did receive a NOTIFY validating the subscription, and continues to refresh the subscription directly to the freeswitch server. The completely breaks presence. What is the correct way to ensure all SUBSCRIBE/NOTIFYs pass through the proxy? I have found that I can force this behavior by modifying the Contact header in the 202 Accepted to point back to the proxy but I'm not sure if this is what I "should" be doing. Thanks for any assistance and please forgive my ignorance when is comes to SIP presence! Spencer

Re: [SR-Users] Siremis login issue

by dave mccann

Hi All I managed to figure out that the table had not been created in the database. So i deleted the install.lock file in the Siremis directory to run the install again. This time I clicked on all the boxes that were on step 2: Create Siremis Database - this create database 'siremis' Import Default Data - this imports initial data into database 'siremis' Update SIP Database - this updates the structure of Kamailio database for accounting and charts modules Replace DB Config - this updates Siremis configuration file with the details to access databases Then after it had finished I was able to login using the default admin/admin. Thanks for the reply Max greatly appreciated for the time taken to do so - Ivan - I didnt get chance to test what you had put however I will take a note of it for future reference.......hopefully I may be able to return the favor in the future if you guys need a hand.
