Yes, they can have the same. While parsing, a=rtpmap takes the highest precedence.
We had encountered a similar situation in iterop where in we had to change the code to take from the a=rtpmap as the precedence, rather than static payload numbers. But yes, if a=rtpmap for the corresponding number is absent, we can go according to RFC 3550/RFC551.

Please check the below SDP format:- m=audio 32420 RTP/AVP 8 0 98 99 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:98 PCMA/8000 a=rtpmap:99 PCMU/8000 RFC 3264 do mention that dynamic codecs must have rtpmap attribute but can they have same name. Please provide some inputs.
