<body>I haven't seen many softphone doing AMR, but heard that nokia's phone do AMR... would be good to have a pcap from a nokia phone using amr to figure it out.<BR>
Sergio and I have seen two different RFC with two different packetization so they changed their mind somewhere ! :)<BR>
Anyways, going from IF1 to IF2 is not a big deal... Just need to make sure which one is the one that is used !<BR>
