Voice latency can be significantly increased since all the RTP traffic has to go through the VOIP providers NAT-proxy. Even if you are calling your next door neighbor, the traffic has to go all the way to the NAT-proxy and back. Just ask one of the FWD NAT-proxy users in Europe what it does for sound quality. 2. The VOIP provider has to pay for all the bandwidth of the RTP steams rather than just the small amount of traffic for call setup. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
