Hello,
I think that append_branch() is not exported directly to lua and calling
it via sr.modf() can expose you to memory leaks
Adding a new branch is possible via pseudo-variable, your sequence of
functions is same as:
$ru = "sip:a@example.com";
$branch(uri) = "sip:b@example.com";
$branch(uri) = "sip:c@example.com";
$branch(uri) = "sip:d@example.com";
In lua, you can use:

That should be safer.
Cheers,
Daniel

I would like to know if there's a way to do
parallel forking via lua
code.
So specifically, I'd like to be able to do something like this:
seturi("sip:a@example.com <mailto:sip%3Aa@example.com>");
append_branch("sip:b@example.com <mailto:sip%3Ab@example.com>");
append_branch("sip:c@example.com <mailto:sip%3Ac@example.com>");
append_branch("sip:d@example.com <mailto:sip%3Ad@example.com>");
t_relay();
except via lua, because the list of branches is dynamic. I've tried the following:
sr.modf("append_branch","sip:10.x.x.x")
but the error message I'm getting is:
/usr/sbin/kamailio[7437]: ERROR: app_lua [app_lua_sr.c:177]: lua_sr_modf(): function
'append_branch' is not available
Just wondering if I "should" be able to do this.
I've been reading http://www.kamailio.org/wiki/embeddedapi/devel/lua#srtm_package but
haven't seen any references to append_branch.
The other alternative I'm looking at is to just use lua to generate the list of
destinations and pass back a hashtable of sorts to
the cfg file. Then from there I will try to loop through the hashtable and do the
append_branch command for each entry
in the table.
If you have other suggestions, I'd appreciate it.
Thanks.
