Goal

Calls Originating from Softswitch are not reaching TDM exchanges of other Region

Call Flow:
Soft-Switch -------> Region1-STPA + Region1-STPB (LoadShare) --------> Region2-STPA ------- >TDM Exchange

From Soft-Switch we have M3UA Links with Eagle Region1.STPA and Region1.STPB. M3UA Link Status is normal. But the End Office status is un-reachable.

From Signal Trace of M3UA :

SS Sends message = DAUD -- Destination Status Audit
ISB.STPA and ISB.STPB Replies with = SCON SS7 Network Congestion State
Then ISB.STPA and ISB.STPB Replies with = DRST Destination Restricted

The end office status is unreachable from Soft-Switch.
