Slot 1 always had a PVDM2-64.
Choppy Voice when communicating between G711 and G729 over a SIP trunk
CUCM6.1 is using the DSP resources for transcoding and conference. CFB is working fine. Transcoding was working fine before we put in the PVDM2-64 in slot 0 in place of a PVDM2-32.
CUCM SIP trunk is using the DSP for g729 and g711 transcoding over the SIP trunk.
