Subject: [EXTERNAL] Re: [SR-Users] Dispatcher attributes

Jason,

My answer applies to the XAVP of the xavp_dst modparam, sorry!

If you are accessing the PV of the attrs_pvname modparam, then you don't need to select the attributes, just directly use the transformation. Also, not sure if you can use XAVPs there, AFAIR it only accepted AVPs/VARs. Maybe someone else can confirm that...

Anyway, to make it clear:

Say you have the following modparams:

...

modparam("dispatcher", "xavp_dst", "_dsdst_")

modparam("dispatcher", "attrs_pvname", "$var(attrs)")

...

Depending on what ds_* function you call, one or the other will be set.

For the "attr1" from your example, you would need to use (again, depending on the dispatcher function called):

$(var(attrs){param.value,attr1})

$(xavp(_dsdst_=>attrs){param.value,attr1})

Sorry for the confusion!

Joel.

Hi Jason,

When you access the XAVP you are getting all the parameters defined. You can make use of the transformations [1] to select an individual value of an attribute.

In your example, it would be something along:

$(xavp(ds_attrs=>attrs){param.value,attr1})

Where you are making use of transformations, specifically the "param.value" [2] to select the value of attribute "attr1".

Hope it helps!

Hi Jason,

We are doing that and it works. I’ll send you a snippet when I get home..

Hi.

When using the attributes feature of the dispatcher module, is it possible to directly access/address an individual attribute directly?

For example, if I use the following dispatcher text file:

--

# line format

# setid(int) destination(sip uri) flags(int,opt) priority(int,opt) attributes(str,opt)

1234 sip:10.10.10.10:5060;transport=tcp 0 0 attr1=red;attr2=blue

--

And this config snippet, I was hoping to be able to access the attribute with a variable.

--

modparam("dispatcher", "attrs_pvname", "$vxavp(ds_attrs)")

if(ds_is_from_list(1234,1)) {

x_log(“L_NOTICE”,”attr1: $xavp(ds_attrs=>attr1)\n”);

}
