Help with SS7 (No Audio)

Hi,

I havent seen any useful information while loading and unloading
chat_dahdi.so, however, I have attached below the output of
ss7linktest and a debug during a call.

By the way, what does it mean when RX is 0 (asterisk not receiving
anything from the telco?)

Thanks
Tim
