Howdy,
I've been hibernating for a while.
What's this?
Call Dialogs :-)
What does it mean?
as in a SIP dialog :-)
I've checked out the docs, is it something that can be used programming for other purposes. Is there an example of a call dialog config file?
Yes, I am currently building a SIP security proxy (SSP) module that uses the dialog modules callbacks to track the SIP dialog life span. Also we will be implementing SIP Session Timer support (SST) soon on top of the new dialog module.
Here is a snippit from my openser.cfg.m4 file that uses the dialogs in the SSP:
... modparam("dialog", "dlg_flag", FLAG_DIALOG) ...
route { ...
if (method=="INVITE" || method=="ACK") { setflag(FLAG_DIALOG); t_on_reply("ONREPLY_RELAY"); ifelse(DEBUG_MODE, `ON', `xlog("L_INFO", "[$mi] loose_route() set dialog flag, set t_on_reply(ONREPLY RELAY)\n");', `') } ...
Now in the dialog module the dlg_create callback is called in the SSP that I registered so I can look at the INVITE message.
The registering of callbacks is done just like the tm module so I will not include an example. The real secret is knowing when to set the DIALOG flag in the openser.cfg :-)
Hope this helps, ronw
