Just in case you have not figured out it yet: you have to change the
RTP payload type on m= line to 8, too. The rtpmap should work,
provided the payload number on m=audio line and a=rtpmap are same, at
least in principle, but most implementations just look the payload
type number for well-known codecs like PCMU or PCMA.
