Dear list, I have an Asterisk 1.4 SIP server and several voip clients in my LAN using Twinkle 0.9-6 and X-Lite, talking among them. I see the following features and I have the corresponding questions: 1) X-Lite 3.0 have SPEEX codec support but only for 14Kbps to 23Kbps bitrates. Can I set a lower bitrate here, i.e. 8Kbps ??? 2) Twinkle has SPEEX support too, and I think it's more manageable because I see more configuration options, I have this: "VAD with Narrow band payload type = 97". What can I know the bitrate configured for this codec here ??? Thanks a lot !!! Alejandro
