The real answer is maybe. If you record raw g.729 you dont need a license becuase you arent encoding or decoding. However monitor may not work this way, it may internally decode even if it doesnt have to, I havent looked so I dont know. You would then only need a license to change the coding scheme (ie from g.729 to anything else) or play the file (whatever plays it at the very least would need a license). In this model you could record raw g.729 frames, and have 1 process, thus 1 license to convert them to something else. But the issue of whether or not monitor would decode (or by using monitor cause something else to decode) would need to be resolved. ranchnetworks.com has network appliances that work with asterisk. These have a calea feature, which basically does port replication on the individual RTP streams that are flagged (ie not everything). It works in two modes, one it sends a copy of the RTP data to a specified IP/port or it just replicates and you can use a packet sniffer. Either mode would enable you to cleanly record without a license, see above for listening. This also assumes that there is traffic going through their switch, becuase well if it doesnt its a little hard for their switch to do anything with it :) -- Trixter http://www.0xdecafbad.com Bret McDanel UK +44 870 340 4605 Germany +49 801 777 555 3402 US +1 360 207 0479 or +1 516 687 5200 FreeWorldDialup: 635378 http://www.sacaug.org/ Sacramento Asterisk Users Group
