On most phones, yes it is possible. Don't be too tight with the number of ports. Give the phone maybe a range of 50 ports or something, keeping in mind that if udp port 12345 happens to be used by DNS (or whatever) and 12345 is in your range for rtp, then rtp won't use that port if it is in use by something else. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
