Hi,I want to know how to do to work PLC of Asterisk. Anyone plz help me. PLC (Packet Loss Concealment) is included in Asterisk,I read at voip-info.org or release note. And I see in codecs.conf, "genelicplc" setting.
So I put codecs.conf in '/etc/asterisk' ,and wrote "genericplc => true". And I worked Asterisk and tested. I think PLC like this. When I send 3 packet (1,2,3), and caused loss (if No.2 is lossed), then receive-packet after PLC should be same number 3 packet(1,2,3). No.2 is new one. I don't know 2 is same sound to old 2,or is zero level sound. But same number packets should be resend from Asterisk to receiver. But when I send 3 packet, received-packet is 2 packet(1,3). No.2 has lossed. No interpolation has been done. So I can't understand how to do to work PLC of Asterisk. Please help me. I tested Asterisk 1.4.* and 1.6.0. Use uLaw to send and receive on SIP/RTP. And caused 5-20% loss from send-packet and through Asterisk ,I checked receive-packet. Is there another things to do without "to put codecs.conf in /etc/asterisk" ? Or Asterisk has no PLC on uLaw ? _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
