[App_rpt-users] what does priority mean

when I connect to my node with iaxrpt I see this in the logs -- Accepting AUTHENTICATED call from xxx.xxx.xxx.xxx: > requested format = ulaw, > requested prefs = (), > actual format = ulaw, > host prefs = (ulaw|gsm), > priority = mine what does priority = mine mean? Does it have to do with what audio have prioroty on the other in a simplex link?
