Hi Stelios! Thank you very much for you reply!
> Does your phone support ilbc as a codec ? Definately. By using to phones and forcing them to use iLBC I can make calls from one phone to the other. The gateway provider does not support iLBC and so * has to do the conversion to ulaw. I've also put a test setup togther with to phones connected to *. One is beeing forced to use iLBC the other to use ulaw. I get the following message: [Apr 28 16:12:40] WARNING[25512]: chan_sip.c:2841 sip_call: No audio format found to offer. Cancelling call to fritz_kiel_oliver2 > Is the codec_ilbc loaded on the * box ? I'm sure the problem is that the ilbc or/and the ulaw codec are not beeing loaded. I've googled for ever to find out how to load a codec but all I found were aticles telling me the * is doing the conversion automaticall. Do I also need to load a translator from ilbc to ulaw? How do I do that? Thank you very much again!
