I am working in AXE-10 switch Transgate. We found that those traffic with calling party address starting from 0, such as 00 or 00853xx or…, all were rejected by switch.
May I know that which part may be involved, Pre-analysis of A-number information or other.
Compare with normal call, no abnormal found, only this parameter is different.
This is not default setting, usually while network integration and implementation, every vendor will ask the format of calling information either local, national or INT, but usually for calling is set unknown, because we don;t know what format the mobile send to network. We only know the called information.
I think, this is basic of MSC features, no patch, but please construct with your local ericsson,, maybe there know the best of your problem.
