Hi Michael, I'm actually using a single IP address. But i'm trying to think of an architecture where multiple freeswitch would be in use, each of them acting as user-controled recorders. The reason i wanted to have the Freeswitch-IPv4 from the dialplan was to be able to include it when defining the record name : Ex : <FreeSWITCH-IPv4>-Record_<caller_id>_<sequence_nb>.wav That way i can get the information of where the recording took place. But in the end i used a workaround : i defined a server_id var in the vars.xml.. But anyway, thanks for the prompt feedback ! Have a nice week-end. Julien ------------------------------------------------------------------------------------------------------------------------------------ Julien, "FreeSWITCH-IPv4" is not a channel variable. Rather, it is an event header. Even so, I'm not sure that an individual event is necessarily the best place from which to be extracting this value. What problem are you trying to solve? Also, how many IP addresses do you have on your system? -MC
