When a hardware transcoder is installed but calls between incompatible codecs still fail, the Release 12.5(1) troubleshooting guide gives as a possible cause that no transcoder resources are registered with Unified CM and directs checking the ResourceAvailable counter of the Cisco MTP Device object in the Real-Time Monitoring Tool.
