In my setup, there's a PSTN line connected to IVR. Anyone can dial PSTN number from outside and once the call is connected to IVR, he can enter the desired extension number. Assume PSTN number is 0114556677 and desired extension is 1000. Is there a way to dial at once this combination. I am not referring to assign DID for each extension. I am looking for a method to dial direct number followed by extension number using special code in between, where PSTN switch will identify only the PSTN number and once the call is connected to IVR, the PSTN switch will pass the extension number automatically.
Example: if the user dials 01145566771000 (Direct number followed by extension) the PSTN switch will rejected the call, because, it's trying the search the full number, where it's not available. But if we can use some kind of special code (please refer X of the below number) in between direct number and extension, where PSTN switch will identify the first part needs to be dial first and the second part needs to be sent once the call connected.
0114556677 X 1000.
anyone has idea what the "X" should be?
