SIP Trunking
 
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.

   GSM Trunking
 
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:
 
Benefits for enterprises:
  • reduce fixed to mobile phone bill drastically
  • provide wireless local loop or 100 % wireless dial tone at better rates
  • provide wireless local loop where no other alternative is available (like for eg. mobile demo equipment or use of phone equipment in regions without PSTN or IP)
 
Benefits for service providers:
  • 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)
  • route customer calls in more efficient networks (eg- into 3G networks)
  • connect all customers with legacy and IP PBXs via QuesCom gateway
