Instead, USSD migration from SIGTRAN to SIP is cost effective solution whereby you keep your existing USSD Gw and everything else is made easy by Procescom.

USSi Gw – Procescom USSD over IP Multimedia Subsystem - USSi Gateway bridges your existing SS7 mobile network with the rest of the internet-connected world and all this without you needing to make any changes to your existing USSD applications and services.

The USSi gateway is a SIP-to-MAP protocol convertor that enables subscribers – smartphone users to seamlessly use existing USSD services over 4G/5G. It also eliminates the need to switch subscribers over to 2G or 3G network to use USSD, which additionally frees-up network signalling and radio resources.
