HSI rejects incoming calls from H323

Network sheme:

ss7network-> as5350-> PGW2200 (v9.4.1)->

-> HSI(4.1)-> H.323 network

Calls from SS7 to H323 network are completed successfully. But if i try to make call in back direction, from h323 to PGW2200 i getting "No_route_to_destination" from HSI. Where is the bug?

Does Cisco_HSI analyse B-number?

How can i fix this problem?

Do you see the call going out SS7 at all? If not, check and see if not, check the EISUP traffic between the PGW and HSI to find out where the call is failing, then grab a .trc file from that device:

Hope this helps.

Re: HSI rejects incoming calls from H323

traffic goes normally from SS7 operators to HSI and then to H323 network.

The problem only in back destination.

Re: HSI rejects incoming calls from H323

Right...For the incoming H323 setup in question, do you see an outgoing IAM on the SS7 side? If you see an IAM go out for this call, that means wherever you are sending the call is sending back the release. If you don't see an IAM go out, the issue is with the PGW configuration.
