Hi When I call from 1 RTC Client to another without Asterisk everything use to be fine but when asterisk is there as a Registrar a problem use to occur in more than 90% calls, Caller can hear the voice of the receiving side but the receiver cant be able to hear the caller for exactly 12 seconds, conversation will become two way after 12 seconds. My Scenario Lucent Max TNT -> Asterisk -> RTC Client API Does anybody ever had this problem ? Any suggestions will be higly apreciated Thanx in Advance ____________________________________________________ Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs
