Hello,
you can use htable module to cache data in memory and access it from
config file or lua script via pv.

Hi Daniel,
I need to access custom database tables (i.e. not default with
kamailio) from a lua script (extending kamailio.cfg).
Processing any incoming SIP request starts with a lua function and
that in turn call other functions - and each one needs database access
for taking routing decision. This seems to be a huge performance issue
(connecting/querying db in several functions for a sip invite).
Could you please suggest
* Any global scope (loads only once during start-up, but valid for
each routing) in kamailio, where the required tables could be cached.
* Or any other way to address this.
Thanks in advance.

Hello,
to rewrite the r-uri you can use the function for setting PV value:
sr.pv.sets("$ru", "_here_is_new_uri_");
To add contact headers to reply, you should use:
sr.hdr.append_to_reply("Contact: <_here_is_your_uri_>\r\n");
Cheers,
Daniel

Hello,
We plan to use Kamailio as redirect server. Corresponding contact
list is to be fetched by a Lua script from DB.
The problem is about calling the required 'rewriteuri' function:
1. From lua script. both 'sr.rewriteuri()' and
'sr.modf("rewriteuri", ...)" fails to write the 'contact' field.
2. I tried an alternative way; pushing the value from lua (e.g.
sr.pv.sets("contact", "sip:...")) and got the value in the
Kamailio.cfg ($var(contact)). But can't call the rewriteuri
function with this variable's value as argument. This seems
to be a general problem of calling a function from .cfg with
a variable's value as parameter.
Any help much appreciated.
