[SR-Users] Group call

[João Vitor Arruda]

Hi folks,

I don't want to hijack this topic, but I have a question related with the
limited number of branches (12) that Marco pointed out.

I too am trying to implement a Call Group in a manner similar to what
Marino described in his post.

Currently I have written code that is similar to the one described here:


http://www.kamailio.org/dokuwiki/dokuphp/tutorials:avpops#serial_forking

The only difference is that for each member I call lookup() and then in the
failure_route(), I pull the next member from the stack and call lookup()
again.  The code works fine when used for groups with less than 12
members.  However, call groups with 12 or more members fails as I can never
reach remaining extensions once MAX_BRANCHES limit is reached.

I've tried another approach using the functions described here:


http://kamailio.org/docs/modules/4.1.x/modules/tm.html#tm.serial_forking

but it too uses a new branch for every group member until the 12 limit is
reached out.

I also tried to use the functions "remove_branch(index)" and
"clear_branches()" (both of which are poorly documented.  In fact the only
reference I ever found for these functions was here:
http://www.kamailio.org/wiki/features/new-in-3.2.x#functions).
Unfortunately, I wasn't able to prevent the MAX_BRANCHES limit from being
reached.

Ultimately, my goal is to have a limitless Call Group.  Do you have any
suggestions? (other than increasing the hard coded MAX_BRANCHES limit)

Thank you,
Joao Arruda
