Sms Sync/FrontCloud responses



I have managed to link my sms sync to my Frontline cloud and also having dynamic responses. Unfortunately, from the FrontLine cloud I do see the expected responses but seems the gateway is not pushing the responses onward to the originating numbers. I am using Webservice to sms. On performing the request it does show {“message”: “success”}. Does smssync allow for dynamic responses from an external web service. After having all messages being pushed and getting processed in the same web service? Thanks
