I'm working on a SIP softphone but I got the following problem and I have no idea how to solve it:During an audio call, PMCA codec is used primarily. How to setup codec priority to achieve PCMU will be used during the call?I use Windows 7, C# (Visual Studio), Ozaki C# SIP library and the following type of codecs: PCMA, PCMU, iLBC.I hope that one of the community have any idea. Thank you very much for any help.
I believe what you are looking for is to change the merit of the filter. This will determine the order of the filter to be used.
I found the following link that explains more about this:
