So when a call is sent to the customer and the customer send us the
correct code for example, we are not able to relay the right code to the
calling party
a call comes from party A through us with a wrong length of digits and we forward that call to Party B, When party B sends us a message that the number is incorrect, our server/switch is not able to relay that same code back to Party A.
So basically then a call comes from the Service provider and transfers it to Customer pBX
and im customer hangup the call or any response i get from the customer pbx, astpp server is not transferring the same response to service provide
Appreciate if someone can help
