I used pri E1 with h.323, C3845 and CCM 6.0 after completed setup I tested call from PSTN to E1 number, I can't hear ring back tone but far site telephone ringing.

After far site pick up ringing,he can not hear I talk but I hear he talk verything.

Which part may be had problem and how to solve ?

Hello,

in Germany the following line on the POTS dial-peer helped.

progress_ind alert enable 8

If you search for this comand on cisco.com there are some examplex etc.
