[asterisk-ss7] Link Up but no audio

Hello Matthew:
I send an call by channel number 1, and I see the audio only in one-way (RX).
[root at pelxsms2voice ~]# dahdi_monitor 1 -vv
Visual Audio Levels.
--------------------
Use chan_dahdi.conf file to adjust the gains if needed.
( # = Audio Level * = Max Audio Hit )
<----------------(RX)---------------->
###################################*
<----------------(TX)---------------->
Rx: 11893 (15967) Tx: 0 ( 0)
So I think, the CIC mismatch is not the issue.
