Hi Rohan, its not a mandatory that delayed answer should add all codec supported in a same m= line of 200+SDP. if multiple codecs are coming in multiple m= lines in 200+SDP then u must add same number of m= lines with respective codec in ACK+SDP.
In non multiple m= lines scenario, u can only add selected codec, in your case it's '0 pcmu'.
