When activating AMR in VSAT sites, I faced problems in Frames Erased and this case can be more seen or detected in case of AMR HR(low codecs). I look forward to find a solution, but it is hard since the AMR HR hopes on different codecs => diff. speed; while the VSAT round trip time is const. Please correct my idea if it was wrong. and i would really appreciate any other suggestions concerning this AMR via VSAT subject.
