(4-Port BRI/1-Port 10/100BaseTx) Our Automatic Dial Converter Series ADC3 device ADC341 for Voice, Fax and Data Basic Rate Interface as well as Voice over IP (VoIP), SIP based.

The ISDN-BRI-VoIP-Dialer ADC341 enables small and medium sized enterprises to make unlimited use of alternative network provider services by automatically dialing carrier selection codes as well as inparallel usage of VoIP without any loss of ISDN-LCR capabilities.

Most telephone systems with basic rate interfaces provide either insufficient levels of features such as Least Cost Routing (LCR) and/or Voice over IP (VoIP) or offer none at all. The ADC341 dialer is the professional and cost saving solution. End user devices can also be directly connected but this devices core application is to be connected to PABXs to use all features with the potential to reduce the number of your current BRI-connections.

Due to the fast call set-up using ISDN lines as well as IP, a transparent dial-in process is ensured.

Like all the other Least Cost Routers by Sonic Telecom, the ADC341 features "Call Blocking" functionality however in both directions: Inbound and outbound. Of course the possibility to admit carrier access codes for pre-selection is also available.
