I found that the problem is cause by the codec. When someone calls XLite (support PCMA and PCMU simultaneously), and Xlite decide to use PCMA, the problem occurs. In fact, XLite will send the PCMU packages, and I guess it makes the noise because Freeswitch does not trans-code. The public server is without the problem, because it detect XLite does not send PCMA and trans-code for XLite. Even XLite (support PCMA) calls XLite (support PCMA and PCMU), a-leg hears noise.<br>
Does Freeswitch support the function which can trans-code the wrong codec? Not everyone knows how to set the codec in the XLite phone, and I want to make sure if Freeswitch can do the same thing like the public server I mentioned.<br>
