dilyanpalauzov created an issue (kamailio/kamailio#4321)

With Kamailio 5.8 this worked: ``` FLT_DIALOG=10 modparam("dialog", "dlg_flag", FLT_DIALOG) ``` In version 6.0 it produces an error: ``` 0(1) ERROR: <core> [core/modparam.c:187]: set_mod_param_regex(): parameter <dlg_flag> of type <2:int> not found in module <dialog> 0(1) CRITICAL: <core> [core/cfg.y:4049]: yyerror_at(): parse error in config file /conf/kamailio.cfg, line 169, column 34: Can't set module parameter ``` and e60a06469503c566d40437e69cf3374 has removed dialog.dlg_flag option. But https://www.kamailio.org/docs/modules/devel/modules/dialog.html#dialog.p.fla... states for dlg_flag:

Note: This flag has beed deprecated and not used anymore. It is not needed to set this parameter and its corresponding flag for initial request in case the “dlg_manage()” function is used. In other words, use “dlg_manage()”.

This is not so correct. If it is deprecated, then Kamailio will still work with it. If it is not needed any more to set this parameter, then it means that the parameter can nevertheless be set. But it cannot be set.

* Documentation should state that the parameter is removed, instead of classifying it as deprecated, and there is no need to set it anymore.
