this DI call would indeed be a very useful addition to sems. i'm
currently using sip router tm.t_uac_wait xmlrpc command for the same
purpose, but would prefer sems, because in sip router tm.t_uac_wait
blocks the process until invite is answered or times out.
it is recommended to set sip router to use a different port for xmlrpc
so sip processing is not affected. Another option is using udp protocol
directly with MI commands.
The other option to implement click-to-dial is using dialog module with
dlg_bridge:
http://kamailio.org/docs/modules/3.0.x/modules_k/dialog.html#id2524918
With the benefit of easiness to use and no blocking, drawback: no return
of the sip reply code for entire operation.
Cheers,
Daniel
