I have a 7940 running 6.3 SIP firmware and make the following type of calls:-
7940 => * => IAX2 <= * <= Digium X100P <= Nortel CICS Analog FXS Both local and remote asterisk's run CVS-02/24/04 (built about 30mins apart). The IAX2 connection is over a VPN, and both sites are running 1500k/256k ADSL connections, about 75ms ping time between the sites. The only time I notice any problems is if one site has an application flooding its upstream, otherwise audio quality is very good. The odd packet might drop here and there, scrambling a word or two, which I usually attribute to upstream choking. 7940 is running G.729 over 100Mbps LAN to Asterisk, and IAX2 connection is presently running GSM (I've bought a couple of G729 licences for the remote asterisk but am waiting on the keys to install the beta codec). Unfortunately I don't have any spare 7940/60's at present to try out on the remote * box to see how a SIP-IAX2-SIP call would perform. _______________________________________________ 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
