'Dialing-in' to Use The Telephone System From a Remote Location
This business telephony application is useful when companies wish to enable employees to dial long-distance calls using company lines, or when several branches of the same company wish to use a single PBX phone system.
Alternative, Low-Cost Call Routing for PBX
Hypermedia's Direct Inward System Access / CallThrough system application creates for corporate businesses an alternative, low-cost channel to dial/call remotely through the PBX to long distance destinations from anywhere in the world; making the most of office-based international / long distance call savings plans.
Reducing GSM Roaming Charges & Call Costs
DISA/Callthrough is designed for users who are making calls from any international or interstate destination back to their home country when using a GSM mobile phone. This business telephony application is a business-class PBX add-on system for reducing overall company telephony costs.
The DISA/ Callthrough & Callback features provide a way to reduce GSM roaming charges and local interconnection rates by providing cheaper call routing alternatives using the PSTN, GSM and VoIP networks.
CallThrough is a corporate callback trigger which enables authorized corporate users outside the office to call a pre-allocated telephone (DDI) number for obtaining a secondary dial-tone from within the organization's PBX/PABX to make calls using the low VPN tariffs.
Ideal for Telecom Distributors, Resellers and Service Providers
Given the applications' flexibility and scalability, this smart Callback application can be pre-configured to meet precise customer requirements so companies can easily expand the cost-effective solution to meet their evolving telephony needs over time.
