Expanding on this comment... The insurance company's customer service staff (definitely not techies) had no trouble at all adjusting to the latency, indeed, they didn't even appear to notice it... They had considerably more trouble remembering how to do a blind transfer to the spanish speakers...

After a few moments of talking the normal person adjusts to it without much notice. Indeed, many overseas links in the past (and present for that matter) are done via satellite.

Out of sheer curisity, the delay itself doesn't make the conversation 'bad' (meaning, walkie-talkie/roger-and-over-like ?) The codec itself should introduce some dozens of ms, but the satellite, is not at least 300ms one way or something like that ? adding the codecs, and the jitter buffers and etc..I wonder how good/bad is it ? _______________________________________________ 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 _______________________________________________ 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 _______________________________________________ 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
