Re: [SR-Users] Suggestion for VOIP Solution

by DanB

That is not entirely true. We use MySQL without any kind of issues via ODBC driver.

understanding the sqlops module and kamailio children.

by Uri Shacked

Hi, Lately i am experiencing some issues with the sqlops module. let's say, for example, that i use sqlops to query some information about the subscriber when an INVITE arrives. I use kamailio 3.3.2, MySQL 5.6 and the DB server is remote and not local. Usually, the DB result is very fast and the call continues. But, when the DB is unavailable, or slow, the result is delayed or lost. In this case: 1. What is the query time out in kamailio? 2. If the database is available but slow, does it mean that no new INVITE will be dealt by the current child process until the sqlops is gone? 3. does anyone has a good idea for managing sqlops in a call? Thanks, Uri

How do I allow any user to register? And why doesn't a call reach the other end in my case?

by Victor Sergienko

Hi, I'm pretty ignorant about Kamailio, sorry for it and possible terminology mistakes. I'd like to allow any user to register. Ideally, I'd like to make some script (Lua/whatever) function to check some data encoded in a username and allow registering based on that username only. I undefined WITH_AUTH in kamailio.cfg, and it used to work for me; but sometimes I'm starting to get "SIP Progress: 100 trying -- your call is important to us ()" and the call never reaches the other party. Here's a sample of my logs during the failed call: https://gist.github.com/singalen/c343f09b67dcf7731fe0 What is the problem here? I start and stop the clients all the time, so there might be some garbage registrations accumulated. I assume I also need a user registration to discard all his previous registrations? Thank you!

$var binary operation

by Jijo

Hi I tried the binary operation using $var as per the documentation and its seems not working. Can somebody help me to understand it. http://kamailio.org/dokuwiki/doku.php/pseudovariables:3.1.x $var(a) = 3 + (7&(~2)); if( [ $var(a) & 4 ] ) { xlog("var a has third bit set\n"); } The format with square bracket in the conditional statement is showing parse error when i load the cfg. So it tried like below and that too not working $var(a) = 8; if( $var(a) & 4 ) { xlog("var a has third bit set\n"); } Please let me know if something missing here.? Thanks Jijo

Call forwarding from external did

by arun Jayaprakash

Hello, I have set up call forwarding in Kamailio using user_preference table. When I make a call from a local extension the callfwd funcition works. The call gets forwarded to an external did number. The problem happens when and external call ( from a DID) comes to this extension the call does not get forwarded. I had to comment out the following lines in the config file to make it work: # only local users allowed to call # if((from_uri!=myself)) { # sl_send_reply("403", "Not Allowed"); # exit; # } My question is if it is a risky think to comment out these lines? If so, what are my options. Thank you, Arun

ice problems

by jaflong jaflong

I am having problems with calls from webrtc to kamailio forwarded to Asterisk These are snippet of the debug logs Asterisk CSeq: 4910 BYE Reason: SIP ;cause=488; text="Not Acceptable Here" Supported: path, outbound, gruu User-Agent: JsSIP 0.3.0 Content-Length: 0 Jssip Cause: Bad Media Description Origin: remote Searching on google I get some indication this is to do with ice config? Please can some one suggest if this is so. In my scenerio the webrt clients will only call to the asterisk server (and not to other user agent). Considersing this I think maybe can do without ice. Is it possbile to disable ice.
