while i configuring CCIE lab, i faced the following issue:
one way audio through the CUBE on R1 between site A and site C when i use iLBC codec:
9971 > Site C R3 > iLBC >> R1 CUBE > CCM 1 > phone
that was because of iLBC packetization issue, when i changed the packetization under 9971 to 30 ikt got resolved but when i used voice class codec it did not work!
any idea !
