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
• IP & PSTN Fallback routing via GSM (works with cost-effective pre-paid card)

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.
