I have an adtran 908e that is setup with two PRI's. When the PBX makes an outbound call, this call goes out and tries to go out to PSTN providing a 404 to the Adtran which is normal cause the number is not assigned anywhere. But then the 404 comes back to the Adtran and the adtran tries to send the call back to the PRI. How can we get that to just stop of 404 is received? Calls originates from T04 goes to T01 and comes back with 404 and then tries T03 and T04 and PBX answers cause the PBX is setup to take any DID... Any tricks on stopping this?
