Re: [Serusers] Need easiest way to set/clear a flag and refer to it later in same call session - sr-users

4 Mar 2009

Please read the getting started documentation from 
http://www.iptel.org/doc. This is a bit old, and I strongly suggest to 
use ser 2.x instead of 0.9.x, therefore some additional documents might 
be also useful: http://www.iptel.org/ser/doc/010whatsnew.

Regards,
Miklos

p.s.
Please post all the questions/answers to the serusers list, others might 
be interested as well.

  Hello,

 for simple and very fast boolean checks you can use the flags:

 - declare the flag(s) at the beginning of the config:

 flags
        FLAG_FOO,
        FLAG_BAR;

 - Call the setflag(FLAG_FOO) and resetflag(FLAG_FOO) functions to set and
 clear the flag when the INVITE is processed.
 - Use "if (isflagset(FLAG_FOO)) {...}" to check the state of the flag in
 the reply route.

 For storing integer or string values you can use AVPs:

 # during INVITE processing
 $foo = "myvalue";
 $bar = 2;

 # in reply_route:
 if ($foo == "myvalue") {...}
 if ($bar) {...}

 Have a look at etc/ser-oob.cfg for examples. The values are attached to the
 transaction in both cases, therefore you need to forward the request with tm
 module.

  I need a simple way to set either a boolean flag
(or integer
 value) during the INVITE of a given call in ser.cfg, and test
 that value via "if" elsehere in ser.cfg during the 183/200
 response messages for that same call.
 This would be a data object unique to a given call,
 which should disappear/lose persistence/end scope when
 a given call ends.  Not global, no need to write the
 value to disk, doesn't need to survive a restart of SER, etc.

 The various SER documents describe a number of things that
 could do this, but most seem overly complex, storing the object
 in a MYSQL database on disk or something, and these all seem
 so excessive.  There also appear to be a few built-in flags,
 but the documentation suggests that all are actually there
 for specific uses and so use for other things might not work.

 I simply want to make a determination of something during
 the INVITE for call 12345, and be able to refer to that
 flag or integer value later on when the various response
 messages for the same call (#12345) are coming back
 through.   I can't make the same determination on each
 message after the INVITE because the original src_ip
 address value where the INVITE came from doesn't seem
 to be in a testable variable when handling reply
 messages, or at least not in one that is clearly
 documented.

 I've chased a number of possible ways this might be done,
 but tire of being referred away from the doc that came with
 the source and over to web sites that tell me this or that module
 that might do part of what I need is deprecated and to use
 this other module, but the web site for the other module says
 that the first module is better suited to what I want to
 do (a circle), doesn't show how the set value can actually
 be tested, or the web page just doesn't work anymore.

 So, assuming there is a simple way to do this, I need a
 quick code snip showing how to set/clear/assign a value to such
 a beast within INVITE handling, and a quick code snip of how
 to test it in an "if" statement during 183/200/110 type
 response messages.  Whatever it is, the value set, cleared
 or being tested in one call should not affect any other
 call.

 Thanks in advance!
