“When transcoding is used with a conference, the transcoder is selected based on the MRGL of the Conference Bridge.”
“Note: You cannot explicitly configure an MRGL for a Conference Bridge. Therefore, the MRGL is taken first from the Device Pool, and then from the MRG default pool.”
The HQ_MRG can contain the software conference bridge , and the HQ_MRGL can contain the HQ_MRG.
