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})
or
$(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”);
}
