The MVC 2050 supports only the G.711 codec with 30 ms payload.
If there are multiple nodes on a system and the same codec is selected on
more than one node, ensure that each node has the same voice payload
size configured for the codec.
Codec configuration
Configure the codec in the DSP Profile sections of TM 3.1 and Element
Manager.
