Hi all!!
I notest that openser has a function avp_subst(). Does ser has a function
with the same purpose?
I saw the function subst() in the textops but you can only substitute
something directly in the message,right?.

New subject: [Serusers] avp_subst for SER + some general rantings about av pairs and lingo...
Note that this is true for SER HEAD (0.10.x). 0.9.x does not have avp_subst.
In SER HEAD, a lot of new (and very powerful) avp manipulation functions
were added. They are created for utilizing the new selector
(@something.part[x]) and the extension of $avp adressing of av pairs.
BTW, the lingo is quite technical, I feel... The @ selectors are
basically pre-defined variables that can be used to address (pretty much
any) parts of the SIP message and manipulate them. Avpairs
(attribute-value pairs) are basically variables (string or integer) that
have a variable name and a variable content. By using $variable_name
you are referring to a variable with a value. This value can be
collected from the SIP message, it can be manipulated and it can be put
into the reply (or the message to forward).
The tricky part is to understand the scope of these variables (main
route, onbranch, onreply, onfailure) and what you can actually do with a
message in each.

Ok, I'll add few words of mine understanding.
There is one major difference between select (@) and AVP($). The select
is READ-ONLY "function", the AVP could be used as variable ('coz is
read/write).
The select helps to get direct access to some parts of request within
the script (like @to, @cseg.method, @msg.["P-anyheader-youwant"]), but
generally could be seen as function returning a string with certain
number of parameters.
Each module can extend the syntax the select framework understands
registering it's own select table. Look on TLS module or db_ops as good
samples.
The AVPs are sorted into classes and tracks:
GENERAL class (same for both FROM and TO track)
DOMAIN class
USER class
with one interesting feature, that the AVP accesse by the track prefix
only is searched in the USER class, if not found in DOMAIN class and
then in GLOBAL class, so you can define GLOBAL value, which is overrided
by DOMAIN (if desired) and by USER AVPs.
Small example could make it more understandable:
# idea in script syntax
lookup_domain("$td","@ruri"); #load domain attrs with to track based
on R-URI
lookup_user("$tu","@ruri"); #load user attrs with to track based on
R-URI
if (!registerd("$t.uid") && ($t.voicemail))
{t_forward_to("","$voicemail"; drop;}
You can set (admin in domain_attrs and user_attrs) when forwarding to the
voicemail is desired or not.
if (... ($t.voicemail)) checks if the AVP exists (in user, domain or
global class) and if yes, it's value is used as destination for
forwarded request.
The user and domain classes are hold together with other data in tm
module, so they are set the same way it were within the on_failure,
on_reply route blocks. All changes done in onbranch route are disposed.
