For GSM V1 FR, the payload type is fixed to 3 in the RFC. But for the other codecs, the payload type is dynamically assigned between 96 and 127. Here, we use a static mapping internal to OpenBSC. This patch is needed to make a rather old 139 unit (with sw version 120a002_v149b42d0) work with something else than FR codec. I also tested this patch on a newer 139 (with sw version 120a352_v267b22d0) to make sure it didn't add a regression. More testing with newer EDGE units should be done by whoever has some of theses.
