Bulk SMS API - SMS to SNPP

We will pass the inbound SMS text messages sent by your customers to your Two-way SMS Service Number (Virtual Mobile Number or Short Code Number) to you using the Industry Standard SNPP protocol. A detailed protocol specification is available from the IETF.

You will need to allow TCP connections to your server on the selected port (default 444) from both of our SNPP servers s3.csoft.co.uk and s4.csoft.co.uk.
