I'm new with voip world and i'm starting to study it, i've setup a asterisknow server and extensions are able to talk between each others but i'm getting crazy how how to enable sip simple messaging.
I want have calls and chat togheter without run a secondary im server like openfire, but i can't find nowhere a guide or an indication on how to enable the IM using sip.
Anyone could help me with it or indicating me the right way?
i've followed all the forum indications on google i found but nothing, i receive this in the console:
