PortSIP PBX and SMS integration

I have setup a PortSIP PBX, I can place Inbound and Outbound calls with a VoIP.MS sub account, I can also send SMS from the iPhone PortSip One apps, but the only problem I’m facing is that I’m unable to received inbound SMS thru the PortSIP PBX. I did all the integration steps from the VOIP.MS Wiki https://wiki.voip.ms/article/PortSIP and also follow the Port SIP document VoIP.ms SIP Trunk | PortSIP Knowledge Base for the Integration with the VOIP.MS API, as anyone be me successfully performed a full integration with success ?

Thanks in advance for your help
