I would like to perform mutual search in java using jain sip application. There is no problem in the register process, but because of codec incompatibility in the search process, I just call and answer the phone, but the call is not sound transmission. . There is a certain codec information in the SDP that corresponds to the invate request that I send to my server. I should take this information and do codecs according to it. Also, payload type values of some codecs are dynamically determined. How to pull these dynamic values and create other attributes. Depending on what I should do a pcma or telephone-event.
I want to use PC8 for video and VP8 for video. I create pcma by default, but there is another codec called telephony event. How am I supposed to do this correctly?

return null;
}
I need to enter the correct payload type value and encoding value at this point, but I could not create the correct media fmtp values or other required parameters in a healthy way. Is it possible to extract audio format values from a location and access both the encoding and pt values? How these values are determined. How can I conduct a mutual meeting
