Interworking Gateway

Interworking gateway provides , PSTN gateway, and trunking gateway.


GSM gateway is a multi-functional product used to effectively implement the smooth transition between PLMN (GSM) and VoIP network. It’s sea blue small appearance, beautiful and practical, easy-of-use to satisfied necessary of customers. It’s a cost-effective gateway for call termination (VoIP to GSM) and origination (GSM to VoIP). It is fully compatible with leading Soft-switch and SIPserver.
