<p>I mostly tested it in conferencing scenarios, using ConfBridge to attach heterogeneous peers. In those scenarios, I used both Chrome and Firefox (using the DTLS-SRTP hacks I mentioned in the other thread), and PhonerLite as well. For other codecs I used a bunch of softphones, our Java applet (wideband speex) and calls from the PSTN using a VoIP gateway. This way it seems to work as expected.</p>
<p>At the beginning, through, I mostly used PhonerLite and Linphone calling each other through Asterisk to test the codec, and I can't recall issues like those you mentioned, but I didn't test this intensively. As I anticipated, I'm currently traveling and won't be able to do any testing until Saturday: I'll keep you posted about this.</p>
