SIP Trunking allows enterprises to connect their PBXs directly to an Internet Telephony Service provider (ITSP) and to extend IP communications outside the enterprise. SIP trunks can offer significant cost-savings for enterprises, eliminating the need for local PSTN gateways, costly ISDN BRIs (Basic Rate Interfaces) or PRIs (Primary Rate Interfaces) and reducing costs for routing calls via ITSP for a better rate.

• offer SIP services without being disruptive to customers
• certified SIP-Gateway connecting BRI/PRI/SIP/H323 for major PBX vendors

GSM trunking will provide enterprises a wireless local loop where there is no fixed line access or where fixed line access is relatively expensive.
GSM trunking is often used also by Mobile Network Operators in countries, where mobile interconnection fees are relatively high and where MNO is not incumbant fixed line operator.

With QuesCom gateways you can offer:

• improve margin on fixed to mobile calls of customers
• reduce churn by satisfying customers with better rates
• route customer calls into less congestioned networks (eg. From 2G into 3G)
