With reference to the ACC documentation link, https://helpx.adobe.com/campaign/kb/sms-connector-protocol-and-settings.html we understand that ACC only supports separated TR-RX mode of in SMPP connector.
Question is, is there any work around for this by going via a bridge middle ware solution to be able to connect to the end SMS Gateway via SMPP TRX mode?
Any documentation/implementation suggestion is much appreciated.
unfortunately, there is no such documentation.
However, something like this could be done with proper knowledge and editing connector .jssp page.
