[Freeswitch-users] freetdm config question

Hello all,

I just had a quick question on FreeTDM configuration.  I have looked 
through the Wiki (both FreeSWITCH and Sangoma) and found a couple of 
references to running T1 boards with robbed bit signaling (RBS), but I 
have not gotten any configuration to work.

Is anyone using FreeTDM with T1 RBS and able to comment on my freetdm.conf?

fxo-channel =>  1-4

I am using an Adtran channel bank (TSU600e) with FXS cards and a 
telephone to try to generate test calls (T1 configured as AMI/D4).  This 
is connected to a Digium TE-220 Dual T1 card.  I am using the Dahdi 
2.6.0 drivers and I have no alarms on the T1.

I am also using the latest FreeSwitch git (as of Apr 17 10am Eastern 
Daylight Time).

Any help or pointers would be appreciated.
